    my wife uses mapmyride on her motorola droid for bike rides. she loses reception when there is no cell coverage.
    i'm assuming on my DX that this doesn't happen because its using gps? or is the gps still based on cell coverage?

    Some GPS apps need to have a network signal to function but there are a lot of them that will work with just a GPS signal. Search the Market for offline map or offline GPS and you will find what you need.

    so my droid gps works just like a garmin, without the need of a phone signal?
    what about google nav?

    You'll need a cell signal to use google nav. All gps does is communicates with geosatellites and retrieve your position by coordinates (longitude and latitude). In order for us use those coordinates, we need mapping programs to map the coordinates to the street we're on. Without maps, all we have are just coordinate numbers.

    In the case of google maps/nav, we use the cell signal to download maps as we go. Without it, we'll have no maps to map our position.

    In the case of garmin or other standalone gps units, the maps are stored in the device for you to use at anytime. That's why they don't need a cell signal to operate.

    Like Airmaxx said, there are apps in the market that have offline maps - meaning you're downloading the maps and storing them in your SD card/internal storage for offline use.

    I use OruxMaps for my offline GPS maps. You need to download the map creator and create the maps for the area you would like to use them in. I have a Google Map and Topographical Map of the area that I use on a regular basis saved to my SDcard. Just go to the "manual" section of the site and there are instructions there on how to create your maps. If you need help just let me know.

    thanks for the nuggets. that was a great description of how the process works. i'll look into getting an offline map.
    i guess that's why when i was using my nav yesterday, the speed was working and the dot was moving, but there was no map to go along with it.
