  • Looking for help selecting the right GPS for me.

    I'm not a fan of the 24k Garmin maps. Also not a fan of the 100k, because in my area they have been very poor. I have a copy of new version that came with my DriveTrack 71. I removed it first thing when I got the GPS and just archived the file on my computer. I put the 3gb of space to better use on the GPS with aerial imagery. One difference with the Overlander is that it has 64gb of internal memory - the most Garmin has ever used. The DriveTrack has 16gb. The Montana 680t (which includes the 100k topo, but not City Navigator) has 8gb, and the Montana 610 (with no maps included) only has 4gb. All Garmin devices can be upgraded with micro SD memory cards but internal flash memory is a little faster to access. As a practical matter, that makes very little difference however.

    Regarding the 24k maps, I think they make more sense for somebody with a device like the Montana 610, which doesn't include any maps. The 24k topo will give you standard road POI's (gas stations, restaurants, etc) and turn-by-turn directions just like Garmin City Navigator. So it can be a multi-purpose map for driving and hiking. As for the contour lines, if you're on foot you typically zoom way in since you move more slowly. I think the contours are probably reasonably spaced at the 300 foot map scale, but if you're driving with the map zoomed at to .2 miles, they can make a mess out of the display. :)

    Have not looked at the 100k topo for a long time, but if you zoom in to 300 feet, I also suspect that roads and trails with have points that are spaced farther apart than the 24k maps, which would show a bit more detail. But I've never looked at maps of Nevada, so I just don't know. And at driving speed, you zoom father out so fine details don't matter as much.

    You can still post photos here the same as always. It's photobucket that changed, not gpsreview. Just find another site that lets you upload photos and link directly to the image files.

    Boyd, thank you for taking so much time to help me out! While I am not quite ready to pull the trigger, I feel like I am getting much more informed!

    Ok, screen visibility is a big influence for me. That alone is influencing me towards the Garmin units. The Drivesmart is out. The Drivetrack sounds like a good possibility and I do indeed want the 100k maps as detail is way up there on my list. It sounds like the Overlander can do the 100k maps too and that it comes with them?

    I have downloaded the user manuals and find them a little lacking in details about what you can load and so on. Perhaps I am missing it, I will continue to read. I am realizing that I could put some map software on my little laptop that I carry with me for planning and playing purposes. It has no GPS but could still be used for looking at maps.

    Well, nothing is ever easy, is it? :-)

    be obtained that way. I often go and find out first hand that a road marked on a map is impassable or no longer exists. So, are there better maps of the sticks available if I go the DIY, make your own GPS route?

    Perhaps a refinement of my question is in order. If going with a purpose built unit, what brand/model comes closest to meeting my criteria above? Or is DIY the only way?
    As someone who has been using GPS and paper maps for many years I can tell you this for a certainty: There is NO SUCH THING as an up-to-date map, be it digital for a GPS unit or on paper. They are all obsolete before they are published. Mother Nature washes out roads and landowners lock gates; many's the time I've created a track to follow only to find that the road is impassable for one reason or another. Google Earth Pro is no help there at all - it certainly won't show you the locked gate on that road. Generally the most up-to-date maps, in my experience, are available from and even they are sadly out of date.

    I live out in the middle of Nevada where there are very few paved roads - if I leave my driveway and drive due south it is 102.5 miles to the nearest pavement. So the remote outback is what I'm used to and it is where I spend most of my time. I am also part of the local Sheriff's Search and Rescue Unit and one thing the members all have in common - they use a Garmin Montana GPS unit because for most GPS functions it seems to be the best overall. You can get an older used/refurbished model for a decent price (I bought one of the first ones that came out and it still works fine despite multiple crashes on my dirt bike and quad). Load the Garmin 100k maps on the unit if they aren't already on it, and then download whatever states you want from At least for Nevada, Utah and Arizona, the Garmin 100k maps show more of the primitive roads than do the Garmin 24k maps. The only advantage the 24k maps have is that they are routable but that's not a big deal for primitive roads. Several of the members also have found commercially available hunting maps to be more up to date and with good detail - but expensive. Download Basecamp from the Garmin web site and learn how to use it with the maps you get - you'll be surprised at how functional this setup can be.

    Ah the search for the holy grail!

    One caveat is Tom Tom Go is in a bit of a state of flux at present with the current release frozen for some time due to multiple complaints. It's just been restarted.

    Good advice from Boyd, keep us updated please. I keep looking at the interesting Carpe Iter but it's a small company and development seems slow to me.
  • Tempe won’t stay connected GPSMap64s

    I'd think the issue is with the GPSmap. When my Garmin Edge does a similar thing with my HR monitor or speed/cadence sensor, It's typically been the Edge device. I'll have to go in an re-pair the device and save the pairing. Typically does happen around battery replacement time, but it's been awhile since I've had to mess with that.

    The last time I had issues though was three years ago. It happened with a new HR strap, I called Garmin and it still ended up being the Edge unit. The Garmin rep over the phone had me do several things and I don't quite remember what or the order I did them. So give them a call and see what they say. Even if you are long out of warranty, they may offer you a flat rate repair that typically is a replacement with a refurb'd unit for a very low cost that might be worth it.

    There is a menu item in the GPSmap that might be some steps you need to go through again..........
  • I recommend Twonav GPS

    Hope for them they will do it. first Spain needs to get out from this corona tragedy, then maybe Twonav will have to open new markets to recover. wish all of you all the best and get back to normal life soon.
  • power and comparison of gps processors

    thank you for these explanations, I always have an "old" Monterra that I keep because it allows me to display all kinds of maps that the most recent Garmin do not display to me / more, in addition I broke one of the legs connection of the batteries, I no longer operate it with batteries, so it is worth nothing ... or almost and therefore it is quite slow to start but I have never had problems displaying maps ,
    I also have an Oregon 750 which displays "almost" all the cards and it is quite fast with the Topo Garmin cards, but I had tested an Oregon 600 and I found the start-up very slow (the screen boot black stayed on for a long time) and I had copied the same cards as on my 750, but I was not satisfied ...
    I called today the Garmin France sav, which did not give me much more explanation and also did not know what was given as specifications on the devices, too bad ...
    they just told me that the most recent gps were more efficient, "necessarily" ...
    I was looking for the difference between an Oregon 750 and 700, I would buy one or the other and I was wondering if the processors were equivalent?
    maybe the 700 has a less powerful processor since it doesn't have a camera to "run", at Garmin they told me that it "should" be the same ... touch screens should also affect processors compared to the 66 range for example ...
    I have an Inreach Mini and I am thinking about buying a 66i, I had the opportunity to try one but I had problems with the connection with my S10 +, when I looked in my directory to send an sms via Inreach, the Explore application had a lot of trouble finding the right contact (I also have a lot) and that made me squarely crash the phone and moreover I find this bulky antenna quite bulky, but the little that I have tried the 66i I was happy with it, I did not have it long, I rented a Mini to try the Inreach system and as the dealer knows me, he lent me a 66i, so I did not want too handle in ...
    I will try to dig a little more, but I think I will take a 750 or 700 if I manage to find tests that suit me,
    I'm afraid of making a mistake with a 66i and I like the Ineach mini, the Earthmate application works very well on my S10 + and I will test it on my S20 Ultra received today, but there is no reason that it is not the same as on the S10 + ...
    I will still test the cards you indicate, I will not buy and resell several devices just to test them ...
    but it's a shame that nobody does tests or comparisons on Garmin, even if they are not devices as sold as phones ...

  • power and comparison of gps processors

    Good morning all,
    are there any databases concerning comparisons for the powers of the processors running Garmin gps?
    we find these comparisons for recent phones, but I have never read anything about these gps, is the 66i more powerful than the other models in this 66 range?
    ditto for the Oregon series for example, I have a 750 and I tried a 600 and I had the impression that it was less efficient, or in comparison is that the 700 is less powerful than the 750 as it is there anything to manage the camera?
    Can touch screens also reduce the performance of the device?
    I was wondering since the maps are more and more complete and the information to be displayed more important.

    thank you for your information if you have any

  • Deleted GMAPPROM.IMG from Etrex20x... free space not created on device

    gmapprom.img is the standard name for pre-installed maps on Garmin devices. If you really deleted it, then it is gone and the memory should be freed up. Are you using a Mac perhaps? If so, the file will not actually be removed, it will just be placed in the trash. The space *should* automatically be released if you copy another file to the device. If not, manually empty the trash in the Finder.

    Another solution is the free CleanEject program from Javawa

    Now, this only applies if you are using a Mac. If you are on Windows, I'm not sure what is going on.
    Hello & thanks - you are right; the Etrex20x was connected to my mac, I viewed the Extrex20x in Finder, I then emptied the Trash and this then freed the space on the Etrex20x allowing me to copy back to same the GMAPPROM.IMG file.

    Great help !
  • Amazing RECEPTION with Etrex 20x

    Which one I prefer depends on the use. The eTrex is smaller, lighter, and has better battery life. It is my preferred unit for things like hiking. With the 64s you can set it to not recalculate a route if you get off route. It also has all buttons instead of some buttons and a click stick. The click stick works well if you are standing or walking but is a pain riding a bike. As you hit bumps in the road and are trying to push it in it will go sideways, up or down. I prefer route navigation on the bike so between that and the click stick I prefer the 64s on the bike.
    As far as the accelerometer, digital compass and barometer that’s a matter of which level of etrex or 64 you get. The eTrex 20 and the 64 doesn’t have them the eTrex 30 and 64s has them. I find I don’t use them if I was buying a 64 today I would buy plain 64 and not the 64s unless I got a good price on a 64s. That’s just my opinion I know others like having the accelerometer, digital compass and barometer.
    I agree with Boyd’s comment on GLONASS that the 64 doesn’t compare to the 62 from that standpoint. The reason I stated that I don’t see much if any difference in the eTrex and 64 is you said the 62 had a better antenna. The 64 has the same or similar antenna as the 62. I don’t think the antenna makes much if any difference. I think the newer unite have better reception than the old ones even with GLONASS turned off and even better with it turned on.
