  • So this gives you all the maps and you don;t need a disk? do you know if this is the lastest version?
    thanks
  • NO and NO and I DUNNO.

    :?
  • Gives you the rather plain MapSource map with no disk required and yes... after you run the updater it will be the latest MapSource files.

    To me it's more of a tool and I use it various tasks that are just easier on the computer, then write it back to the nüvi.
  • Hi, I'm new to this and followed your steps and it works! (Thanks Xopher!)

    However I live in South Africa and purchased a nuvi 310 with the Southern Africa map on SD card. When I go onto Mapsource it only gives me the "rather plain mapsource map".

    How do I go about getting the map from my nuvi onto Mapsource so that I can have more detail. Do I have to unlock the map and if so, where do I get the code from (I don't see one on the SD Card).

    Thanks to you and Tim for a brilliant site!

    P.S. would be great if there was a thread in reviews for the nuvi 310.
  • P.S. would be great if there was a thread in reviews for the nuvi 310.
    Start a thread for that if you would like. The 310 wasn't available in North America so there hasn't been as much discussion about it here.

    Wow! That was easy! Thanks for the tip!
  • What exactly is Map source for??? I quickly looked on garmin and didn't see much about it... I went to mapsource.com and it looks like they sell paper maps...

    I'm sure that a dumb question, but I'm new to GPSes and still learning my 760, its functions and uses...
  • MapSource can be used, with some devices, to plan routes on a computer and transfer those routes to the GPS.
  • I just updated the maps on my NUVI 780 and I got somthing called MAP INSTALL...weird it lists the lower 48 and you can click on a state and I guess upload the map to your device? I don't know what this is for...I 've looked at it but don't see what to do with it.
  • edited September 2008
    I download and opened the first program.
    I download and opened the second program.
    I get an error, ~us topo missing, program closing...

    If I open the training center, it wound locate my 780? If I select find a new device, I get an error...

    If I check for updates, sez, none available...
    If I Check about,
    Product info, I have 3.4.3
    USB, no drivers installed (it went through the process?)

    Update, then download mapsorce,now works fine...
  • Does anyone know if MapSource is compatible with the 260?

    Thanks,
    Bill
  • MapSource is "compatible" with nearly all Garmin devices. But it won't add any new features to your device that don't already exist. For example because the 260 doesn't support saved routes, you can't create a route in MapSource and transfer it to your 260 like you can other Garmin devices that do support routes.
  • I purchased a Garmin 750 a week ago from Sam's Club. It did not, of course, come with the Mapsource DVD. I emailed Garmin and mentioned that fact and asked if they could assist as I wanted to be able to plan routes on my Mac and import them to the 750. They said a copy of Mapsource would be sent to me without delay.

    That's great service and one which completely surprised me.
  • Talked with a Garmin technical expert last night. He said you first need a MAP on your PC and then you can download Map Source from their web site for free. I'm getting the 2009 map next week so we will see if this information is accurate. Can anyone confirm?

    Tim
  • That would be basicly correct. Just not completely sure of the free part. Mapsource is simply a software program and does not come with an included map (tho the DVD version I have did include one). A matching map needs to be resident on your computer. When you download maps from Garmin, a copy is first made to your computer, then sent to your connected nuvi. Mapsource would now have that copy on your computer to use.
  • Am I reading correctly that there is no way to get the map from the garmin to the computer? I haven't updated my map or anything since I just bought it (the garmin website says it is up to date). So do I technically not have a map to download to the computer?
  • Loaded new map onto PC, loaded new map into GPS, downloaded Map Source, and everything works. Pretty simple.

    did it and all i got was the basemap. missing alot of roads in between the majors. am i missing something? have the nuvi 850.
  • This process gets you the application, but doesn't get you the maps from your device on your computer and unlocked.
  • so is it useless? how to unlock? they want $15 for the dvd. i am newbi to gps, i am learning as i go. what i want to do is what the original post wanted. customize the route with the roads that i want to take, not what the garmin suggests and save them to the device. just buy the program and be done with it???

    thanks
  • Yes, just spend the $15 and be done with it. Easy, supported, legal.
  • Yes, just spend the $15 and be done with it. Easy, supported, legal.
    great, thanks. will do!
  • sent an email a few days later saying that i spent almost 800.00 for the unit, thinking the 15.00 program should be free and i will get it for free in 3-5 days. persaverance pays off!!
  • Just curious what anyone who already had 2009 maps on a nuvi received, actual NT maps or just Waypoint and Trip Manager (Mapsource with basemaps)?

    I instead bought Topo USA 2008 just to get some maps with Mapsource to plot points/tracks on my PC from my 750 (or old GPS 45 w/o maps), since I also do things out in the woods.

    Although, I recently bought an eTrex Legend HCx on Ebay bundled with City Navigator NT (2008), DC power cord, suction cup mount. After I registered at Garmin I was able to order 2009 map update no charge via 1st class mail. So I now have City Navigator NT 2008 on my PC and will have 2009 when updates arrive.

    I only had the base map... very limited data set... Here's how I got around it and now have the map that came with my GPS in MapSource

    Your 850 should have a map installed.

    If you look on the Flash drive via USB, you should see a huge file ~ 1Gig in size. Mine was called gmapprom.img.

    Copy it to the directory where the base map is located:
    c:/garmin/pcbsmp2/pc_basemap2.img...

    Rename the pc_basemap2.img to something else, like: pc_basemap2OLD.img.

    Finally, rename the map file from your GPS to pc_basemap2.img.

    Run MapSource and you should see all roads and points of interest etc...

    I have a Nuvi 255. Followed instruction here, loaded map from gps to pc and changed name. But no detailed map. In my gps, there is also a gmapprom.sum file. In the mapsource, there is a pc_basemap2.tdb file (1KB). I suspect I need to change my .sum file to .tdb?

    TIA,

    I didn't have to change any other files, on the nuvi or in the c:\garmin\pcbsmp2 sub directory. Not sure what to tell you. Have you exited from MapSource and restarted it? I guess double check that the map from the nuvi made it to the pc correctly... and is named correctly...

    Anyone else have any thoughts?

    One other thing you can look at is:

    In MapSource, in Edit, in Preferences, in Default File Location: Make sure that it's not pointing to some other directory.
  • Thanks for your response. I do see some detail map, but there are big batches of blanks on the map screen, as if some part of the map is missing. Also, when I tried to do routing, it would only allow me to connect from point to point with a straight line. There is no item in edit->preference to change the routing method as in the help pages.

    Finally, I think I have problem with the installation. I have gStart on the quickstart tray. When I click on it, it says no gps detected. But I can see the nuvi255 from the windows explorer. Also, when I installed the training center, it ask me to plug in the usb cable into the pc with nuvi255 started and connected to the other end, and wait for windows to install the driver. But, I waited for a long time, and there is no activity, so I click next, and it finished installing training center. Maybe that is why gStart did not detect the nusi255.

    Please advise what I can try next. I have tried to install, uninstall many times, but the same result as above.

    Not being any kind of expert here... I mostly just try things...

    I do notice the same thing with the maps being displayed in chunks. But that's only when I'm zoomed way out. Like for instance: When I'm at a zoom level of say 100 miles, I can pan around 1 state, but when I get near the edge of that state I see some blanks space where the next state should be. If I pan over more, the first state goes blank and the new one displays correctly. I believe it's the program memory management.

    Routing (calculating a route (driving directions) from point A to point B) doesn't seem to work for me either.

    The Find, Find Places is kind of quirky also. Sometime is work, sometime not.

    As for gStart, I have the exact same thing happening. I haven't bothered trying to "fix" it. I just as soon have it go away. I'm not even really sure what it's for. I can connect the GPS to the USB cable and "see" the drive, transfer files etc... so the USB connection is obviously working... Yet gStart say there is no GPS connected.

    I think Garmin has way to many products, and they are not able to support them all properly.

    I was just happy to be able to see the maps. That and to be able to upload tracks, waypoint, geocaches etc... to the GPS, and to be able to download GeoCaches to the GPS. It would be cool to create driving instruction in MapSource and download it to the Nuvi. Not really sure if that's possible.


    Sam
  • Sam, thanks for your response. You really put me at ease. I now realize gStart is likely for a USB GPS, not a handheld like ours. That is what it says. I think I will move on and try routing in google maps and download to nuvi255.

    Why didn't I have one of these when my kids where 16 and just driving? :)

    Atta boy !
  • I'm having a problem...

    I'm having troubles getting a current map to work with MapSource. I have a map update (That I cant use - see below). Someone posted a, how to copy a map from your gps (or elsewhere. As long as it has that has the 'img' extension), and renaming it to the, original name of, pc_basemap2.img (found in the, Garmin\PCBSMP2).
    All this to get a real map. Anyway, I did this with some success.
    However, wile experimenting, I copied over my TOPO map. It overlaid the basic map (incorrectly), and remained even though I erased it. So I copied the 2009.0 file and this worked, however, the bad TOPO remnants remained?
    Next, I deleted the c\garmin folder, and I deleted the trash, went to the, add and removed programs tool, and removed both the trainer and mapsorce programs. And rebooted.
    Finally, I reinstalled both programs, and the collage of maps remains???

    What am I doing wrong?

    Note: I have 2009.0 map update, but it from my previous 780 that was returned do to a dead battery. So the map program wont run because the serial numbers differ.

    Update...
    For the scrambled maps: Select, "less detail." Then back to "most detail," this redraws the map.
    I found out how to fix my missing map problem:
    (With the map update DVD, in the appropriate drive) Using windows explorer, go to the DVD drive, folder named, "windows," next, "msi," finally a file named (click on) CNNANT2009Update_ENU.msi
    MapSource now works fine...
  • Thanks for the update link. It's works for ver. 2.0 up to 6.+

  • I have used Sam's trick successfully: I first got Mapsource then was able to transfer the map from my GPS unit onto my PC and use it in Mapsource.

    Question: I intend to buy additional maps (Europe) on SD card. Will I be able to load them on my PC in the same way?

  • I have no problem downloading and installing The Training Center site for MapSource. However, http://www8.garmin.com/support/download_details.jsp?id=209
    sends me to a download of Map Source Safeware Version 6.15.6. When I try to install, I get the message "previous MapSource not found! Setup will terminate." What am I doing wrong to install MapSource?
  • This thread is getting old and links have probably changed. This might be a safer bet for long term use - all of Garmin's mapping software should be listed on this page:

    http://www8.garmin.com/support/mappingsw.jsp

    Sorry... after reading your post again I realize that "safeware"=software. That had me confused!

    That does appear to be the newest version. Are you sure that Training Center was properly installed? Maybe they have changed something in Mapsource such that the update no longer works without a previous version installed? Sorry, I don't know, but others have done this without problems during the past few months, so if something has changed then it's recent.

    Maybe Garmin finally got annoyed that people are using Mapsource to work with free third party maps, when it was really designed as part of their own products. :?
  • ......Maybe they have changed something in Mapsource such that the update no longer works without a previous version installed? Sorry, I don't know, but others have done this without problems during the past few months, so if something has changed then it's recent.......
    Nothing has changed... I just installed it on a new laptop a few hours ago and everything works fine. I downloaded and installed Training Center, downloaded and installed MapSource, copied gmapprom.img from my nuvi 780 and renamed it pc_basemap2.img on my laptop. MapSource is working great with the full 1.1GB CN NA NT 2010 map displayed complete with all POIs. Good stuff!
  • Thanks for the update Seapup!
  • Hi,
    I am new to GPS and MapSource. When I install on my desktop with XP Media Center I get a lot of gray areas on the map. Didn't get to try any routes. I think Media Center is the same as XP Pro. I did remove and reinstall. Any suggestions?

    JimB
  • What are you using for the map? Is it the full City Navigator map which you purchased on DVD or via download? Or did you try to "rip' the maps from your GPS?

    There are issues with ripping the map from the GPS and this is something which Garmin doesn't support.
  • Yes I ripped the map off the Nuvi 760. Since then I did the same thing on my laptop with Vista and all seems to be working.
    Thanks for the reply

  • Just to echo that this technique still works (the technique of the original post) For the guy just a few post back (dmillermail) I was walking a friend through this from across country. He got the same message so we started over again. Apparently, when he thought he installed the "training center" he didn't do something right and it didn't really install. The second time it went all the way through the installation. Then the update process of MapSource's latest version downloaded and installed as expected. From what I see, you can only download the update if you have a current MapSource product on your computer. The free "training center" qualifies you for the update. This friend of mine had a MapSource disk that came with his GPS but never used it because I always took care of his maps for him. Now that he needs to do it on his own he can't find the disk (after a traumatic post divorce property move). I think Garmin wanted about 25 or $30 to replace it. Also the links on the very first post of this thread are still valid, and the ones that we used.

    I am having a hard time installing this. I used this link to download the training center.

    http://www8.garmin.com/support/download_details.jsp?id=835

    I then installed the training center until it to me to attach my device and I just clicked "Finish"

    I then downloaded the Mapsource:

    http://www8.garmin.com/support/download_details.jsp?id=209

    I am having two issues. When finished installing, it Prompts for "Launch MapSource Now?"

    After running it, and closing the program, it is not installed. Everytime I want to use it, I have to re-install it.

    My Main proble is the map. I attached my Garmin Nuvi 760 to my PC and copied my GMAPPROM.IMG file to my harddrive. It is just over a gig. I then renamed it to PC_BASEMAP2.IMG and put it in the c:\garmin\pcbsmp2 directory. It will not load. Trying to run mapsource says there is an error with maps and if I say run anyways, it will just open the generic map.

    In looking at what was there originaly, not only was there a PC_BASEMAP2.img file, but there was also a PC_BASEMAP2.TDB file. I have no TDB files on my nuvi 760 to copy over.

    Any ideas on how I can get this to work?

    Thanks !! Just uploaded the NW Trails and 24k Topo maps to my GPS. :D
  • I know this is a dated thread, but thought I'd add my input and ask some questions of my own.

    I am a past user of MapSource, and have been using it for several years. It came with my Garmin GPS-V. I currently have it installed on an older machine that still has serial ports, just so that I can talk to my GPS-V. Over the years I have updated MapSource, but I have not updated my map set. My data is several years old and really out dated. I've never bought updated maps, because for the most part, the old maps work fine (although the outdated info does occasionally bite me in the butt). At the time, new maps costs more than a new GPS unit.

    Which is why I recently bought a Nuvi 780, to get new data. If I'm gonna pay all that for new data, I may as well get new equipment with it.

    I followed the tips above with MapSource and tried to swap out the old data with the new img file I obtained from my Nuvi 780. Since my old data set is configured a bit differently and points to things in different directions, it didn't quite work like others found it to work. However, I was able to poke around and with the knowledge of how others did it, tried some things and managed to get it. So now it works. Sorta. I can live with the map "Chunks" and how it is displayed in an odd fashion. The problem however, is that the Map-Tools selector icon no longer works. Well, the icon works but it will not allow me to select any portion of the map. Not a big deal for use with my Nuvi, but my old GPS-V relies on maps being loaded FROM MapSource onto it's massive 19MB internal memory (yes, I said MB). Without this ability, my GPS is "Stuck" with whatever map data I sent to it last. With only 19MB of memory, that is usually just two or three counties. It's a PITA, but that's how things used to be (and if you're using a GPS-V, how they still are). So the MapSource with new map data from my Nuvi 780 works fine with the Nuvi (or any other modern Garmin I presume), but is only a one-way-street with my GPS-V (and it desperately needs to be a two-way street). Without the map selector tool, I can't really use it with BOTH my GPSes.

    I know I'm bending the rules (or at least trying to) and what we're doing with the maps is probably a gray area at best, but does anyone know of any tricks or tips to help me with this issue? I'd really like to use the same maps/MapSource with both units.
