Backing up a 3790t...worth it?
  • sviking
    Posts: 1,042
    Title says it all. Years of faithfully backing up my Nuvi 660 and never needed it once. Worth it with the 3790t? If it gets corrupted or something important deleted, will it really "restore" it back to full health by just highlighting/copying everything back over to the unit? I never tested a restore on the 660, so I have no idea if it would work. Yes, I had it set to back up the hidden files as well.

    I've paid for home owner's insurance for 45 years and never used it either until we had a broken water line to our dishwasher last fall and the bill for the repairs was probably pretty near the total amount of premiums I"ve paid on the insurance over the years.😃

    I'm in the same boat as you though, I've faithfully backed up my 350, 780, 1490, and 3790 plus 2 TomTom's and never needed anything from the backup except an up to date current.gpx file. Never the less for the time it takes I continue to take regular backups.

    You'll notice a big difference in the time needed to backup your 3790 compared to the 660. The 3790 uses "Garmin's version of USB 2" so it's really a lot faster for file transfer etc.

    Thanks for the response! Backing it up now... Says about 30 min while my 660 took about 45min, but I'm guessing there's a LOT more stuff on the 3790t to back up. I did delete all the unneeded language files.

    From years of experience, after purchasing any gps unit a backup is the smartest thing to do. Anything can go wrong and a hard reset will not reintroduce the original files you had.

    Nope, not always. I've done several "hard resets/erase all user data" after firmware and map updates. All my favorites were still there, which was entirely strange since one would think that's USER DATA...

    When you send favorites to a Nuvi with a program like Mapsource, they are placed in a file named Temp.gpx. Then when the Nuvi restarts, it imports everything from that file.

    When you do a hard reset, it erases all of your favorites. But if this Temp.gpx file is still resident in the GPX folder from a previous Mapsource transfer, it will be imported again.

    This is actually kind of a sneaky thing that I learned the hard way once. I was surprised, but pleased, that my favorites weren't removed after a reset and headed off on a trip. About halfway there I noticed several favorites were missing. Then I realized I was seeing an old version of my favorites that didn't include the ones I had added on the GPS itself. They were wiped out with the reset, and the older favorites were re-imported.

    Honestly, I can't think of any reason not to do a full backup of a new unit unless your hard drive is almost full. You never know what you might wish you had later...

    That's interesting Boyd that the favorites from Mapsource aren't deleted when you clear user data. I took the trouble a while back of copying all my favorites to Mapsource and then putting them into categories such as Hotels, Family, etc. Then I copied them back to the Nuvi.

    Now whenever I do a reset none of my favorites are deleted. I always assumed that this was because for some reason the fact that they were in categories was the reason but it's probably, as you say, because they all were transferred to the Nuvi from Mapsource.

    I don't think the reset removes any .gpx files, does it? Take a look at Temp.gpx and note the modification date. That may solve the mystery. I don't use categories for favorites, so I'm not sure how that affects the mix.

    I directly copied the current.gpx file from my 660 to my 3790t when I first got it. I also added some favorites directly on the unit. It's never been used with Mapsource. I did a hard reset after getting my free 2011.40 map update and updating to firmware 4.10. All the favorites are still there.

    Just checked and all my loaded custom POIs are still there, too. Weird...

    Copying Current.gpx shouldn't have worked to import favorites; are you sure? I think you need to change the name of the file to anything BUT Current.gpx.

    If you did that, what did you name the file and did you delete it afterwards? If there is ANY .gpx file on the Nuvi (other than Current.gpx), it will be imported following a reset.

    As for the rest, I dunno. But I am quite sure about the story I related above, because the favorites I created directly on the Nuvi were gone but the old ones were still there.

    I don't know, but it did. Just copied it from the 660 backup folder on my computer and dumped it in the GPX folder. There's three files there. Current.gpx, position.gpx and some .lpt file with a bunch of numbers. All the favorites from my 660, plus the ones I added, are there.

    On another note, since this thread is getting some traffic and my other one isn't...

    Anyone have ANY route I can simulate where I can actually see some junction views? I've been simulating routes all over the place and haven't seen a single one yet.

    Well if you have 2011.40 maps and firmware version 4.10 your going to be disappointed as the most you'll ever see on a route is ONE and that's the first one you come to. There is currently a bug introduced in 4.10 that prevents all but the first view on a route from being shown on the map screen.

    If you set your 3790 in simulation mode and input the following route you will see 5 junction views by tapping the green bar at the top of the map screen and then the top entry in the list of turns that will appear. Press the down arrow to see each turn including the 5 junction views:

    With the Nuvi in simulation mode enter Where To? - Address - County or Country and enter Canada. Then enter Ontario as the Province and Search All. Now enter the address 3401 Dufferin St and pick the one listed for North York, ON, M6A. A map screen will appear with GO in the bottom right corner. Tap the 3BAR icon in the upper left corner and then Set Location

    Now go back to the main screen and tap Where to? - Points of Interest - Transit - Air Transportation and select any of the Lester B Pierson entries you see listed. Press GO.

    Then say yes to simulate the route. On the map screen as the route is traveled, press the green bar to get to the "turns" screen. Tap the first entry and then the down arrow on the left hand side of the screen to see each turn in the route. A JV will be displayed for every turn in the route that has a view in the map data - 5 in all for this route.

    So, if I "downgrade" to firmware 4.00 or earlier, will this fix that issue?

    What a bunch of BS...AGAIN...and I'm talking to YOU Garmin. 😵

    if you think downgrading the software will help you view more junction view.it won't. Some cities have more JV then others. The junction views get updated with every map update.

    No, you completely missed the point. I'm not talking about "unlocking" more junction views or something from what are already in the database. I'm talking about being able to see more than the FIRST one on a route with more than one junction view.

    The simulated route given to me up in Canada has five junction views on the way to the airport. With firmware 4.10, only the first one shows. I downgraded to firmware 3.9 and now I see all five when simulating the route. Garmin needs to FIX this (among other things) in their next firmware revision...if there is one... :roll:

    Really? Interesting. Hope they release a "new and improved" 4.10 sometime soon. :roll:

    If history is any indication you will never see 4.10 again. When they release the next update it will be 4.20 or higher.

    HERE's a real friggin' gem from Garmin. I just received a response to my question about why 4.10 was jacked up and when they were going to fix it.

    Straight from the source... "No rhyme or reason" as to when they do software updates??? Guess we'll have to wait until the 3790t is discontinued until it's, ahem, "generally working well". :roll: :evil:

    Dear ,

    Thank you for contacting Garmin International.
    I am more than happy to help you with this.

    There is no rhyme or reason as to when the system software is updated. If the device is discontinued, much like the 600-series is, we stop producing software updates for the device. Generally, by the time of discontinuation, we have the software for the device working well.


    With Best Regards,

    David Du.

    Whatever...same same... As long as it's "better" than 4.10. I guess I'll NEVER say "fixed" again in regards to Garmin firmware...

    I am happy with 2.6. Doubt that I will ever upgrade beyond that.

    But that quote from Garmin isn't even factually correct. They have continued to release updates for discontinued models in some cases. They introduced an update for the Nuvi 660 in March 2010 for example:

    http://www8.garmin.com/support/collection.jsp?product=010-00540-00

    I know. They also released an update for the SP 2720 giving it a QWERTY keyboard option after they were discontinued. I was VERY vocal about that one on the forums and to Garmin since I'd recently purchased a Nuvi 660 (fall-2006) and they wouldn't (and never did) offer the same update/feature for it. Absolutely NO reason for not doing it, either. I'll bet the code was 99% exactly the same as the 2720 update. All they had to do was "re-matrix" the same keyboard.

    Also, please see the new thread I just started, with Garmin email response, about them NOT fixing the Mapsource compatibility issued with the 3790...

    Hi Boyd, I didn’t know Garmin released a 2.60 for our 37xx models. It’s not on there page. http://www8.garmin.com/support/download_details.jsp?id=5063 Do you have a download for it so we can try it?

    I don't have my 3790 here and just posted that from memory. Maybe it was 2.5 or ??? It was the second firmware version they released IIRC. I can check tomorrow if anybody really cares.

    I've done quite a bit of searching and have only found 2.5, 3.6, 3.9 and 4.0 for download, as of today. 4.10 appears to be history as of the 28th.

    OK, my mistake. It was 2.50: http://forums.gpsreview.net/discussion/21369/x/p1/

    It works OK for me, and the only features that I might want would be the map scale on the main screen and the ability to disable autozoom. But I don't want to switch countries just to have the autozoom feature. And all the new bugs just aren't worth it for me.

    I also disliked the change (in 4.0??) to the sleep function which always puts you on the Where To screen on wakeup. I have not confidence that Garmin is going to get things right in the near future, so "better the devil that you know...." :twisted:

    I've settled on 4.0 for now. It doesn't do that. It takes you back to whatever screen you were on before sleep mode. It even remembers if you were in portrait or landscape view before staying in that view or switching to the correct orientation after about a second.

    Do you notice "jittery" graphics that are not as smoothly aliased out towards the horizon in firmware 2.50? I did. 4.00 looks a lot better. 3.60 is when they made that change...I think...
