I've have a few GPS units 2 that hook up to laptops, Garmins model 5, 12, Nuvi and Cell Phone one. I have used mil ones that is about the same as the model 12. In 2003 was issued a Plugger GPS, my model 12 was faster picking up signals and more accurate..
But I was using a map I bought in a gas station in Kuwait to get around in Iraq
no I'm not joking.. I looked at the Plugger and said what do I need it for. I've seen Mil and Civ GPS units get more people lost, and lead people to closed roads and bridge outs.. 08 in Iraq the mil system in my vehicles would show just a blank screen with no road/ terrain data at times. 15 Jun I was using GPS and ended up having to back track 25 miles due to it leading me to a road closed bridge out, bridge washed out over 6 months before this is after it being updated. I use and keep maps. can plan routes better in most cases, avoiding traffic and other problems. I learned not to trust GPS and "Map Quest" in 2000 Map Quest directions from San Berndino Ca, said to go west out of Airport when traveling toward Death Valley..
This is why I'd rather depend on Maps. Cell Phone = electronic leash
best and worst thing I got.. My first one back in early 90s
