  • Information on Birds Eye and SD Card

    This is an old thread, but my numbers should give you some idea of how much coverage you can fit on a card.

    http://forums.gpsreview.net/discussion/comment/126239/#Comment_126239

    Rounding off... figure about 2.5 MB per square mile for the highest quality imagery. So that is about 400 square miles per gigabyte. So, theoretically, you could fit 25,600 square miles on a 64gb SD card. That would be the equivalent of an area 160 miles x 160 miles.

    Now my subscription expired a long time ago, and I know they have made some changes. But according to my old thread, there are 150 image tiles per square mile. I think you will probably hit some other limits before reaching 64gb - that would be almost 4 million tiles and I doubt your device can handle that many, regardless of the memory card size.

    I have a 16gb card that is full of birdseye imagery. When I insert this in my Montana, it takes forever to start up, which I found unacceptable. You will have to do some experiments to see how much imagery actually works well on your GPS.
  • Drive Units add new Trip Data Options

    The image in your post shows for me. I assume you know this, but the way to post an image changed when Tim updated the software (several years ago now). You need to click the little picture frame icon, then paste the URL into that box.
  • How to update a nuvi 1300 with lifetime updates when I only have XP computers??

    It's great that you got it working. The last time I tried it would hang part way through the download and I finally gave up and used Express.

    If you look at the link @t923347 posted, it shows two versions on the Nuvi 1300. Am guessing that you have the version that included the full North America map along with a lifetime update card. I used to have a Nuvi 1350 which was like the other version that only had the "lower 49" map and no updates.

    I have wondered about whether Garmin is strictly enforcing the new 2 year update policy. Some people have reported that they are. I have a couple old units myself (Nuvi 3550 and Dezl 760) that have not been updated for a long time so maybe I will try someday and see what happens. Have pretty much given up on them though, my phone is much better with the Garmin StreetPilot app which looks just like a Nuvi.

  • Cheap, barebones hiking GPS... Do I have to go used?

    I've read that people are using these with no SIM card or data connection as a replacement for a dedicated GPS, specs are impressive and street price a little over $100. No personal experience with them though.

  • Cheap, barebones hiking GPS... Do I have to go used?

    The cheap phone isn't a bad idea. But if you want to buy a used GPS, you could look for one of the old eTrex H series

    The Vista has a compass and altimeter, the Legend does not. Both use the so-called high sensitivity gps chips (as compared to the regular eTrex Vista and Legend that had the older chipset).

    Have not looked at pricing, but these are probably the cheapest models with decent chipsets. Of course, it's hard to say what to expect from an old model unit like this, it would be ideal to see it in person but that probably won't be possible. There were various things that broke on these old devices, such as rubber gaskets and switches.

    Perhaps you will find good pricing on used Magellan units, they don't get much love. ;) I have a Magellan Triton 1500 that I never use anymore. It has the same SiRFStar chipset as the Garmin GPSMap 60csx which is still very popular (and ridiculously over priced in the used market), I also have one of those.

    If you want something more modern, the eTrex 10 has the latest technology chips with GLONASS so you will receive more satellites. It has a monochrome screen and cannot load maps. Looks like Cabellas has it for $80. Perhaps you can find a factory refurb for less (Garmin refurbs have the same warranty as new).
