Summary: I've just bought this gps , and I'm gonna tell you I'm totally dissapointed with this unit.At the same time my father bought a Garmin eTrex unit and it's much better. I now regret all the fun I've made about his GPS and mine because mine has 18 satellite connection and his just 12.
Summary: The bargain GPS I got seemed to work fine on the trip home from town, except the build in maps only list major roads.I spent the money on the interface cables, power cable and mapping CD roms only to discover that the 500 will not allow map detail information like roads to be uploaded!
Summary: Repeating the sentiment of the earlier reviews? Yes, I am. Important to do so? I'd say, yes, it is, since you might think the other three reviewers were just unlucky. The Cobra 500 is absolutely useless. It locks onto the required 3 satellites ... sometimes. Usually not.
This thing is really as bad as all the other reviews say it is

Summary: I purchased a GPS500 for geocaching, mainly attracted by the low price and "FAST" acquistion feature. Screen resolution is terrible, acquisition times vary from 6 minutes to never, accuracy (compared to friends' GPS units) was way off, and it proved to be utterly unreliable in the field.
Summary: The unit works brilliatly as a paperweight to hold your map in place so you can orient by compass. First time out with the GPS as our guide, we stayed lost for 6 hours. Stupidity on our part to be sure --- for getting lost in the first place AND for thinking the Cobra 500 would do a lick of good...
Summary: I purchased (through the Air Miles rewards program) the COBRA GPS500, not once, but TWICE. I first purchased the unit and believed it to be faulty it performed so poorly. Signal acquisition time seemed "forever" and it frequently lost satellite lock.
Summary: Recently upgraded a cobra 100 for a 500... first time out, it failed, leaving me in the woods all night 'till I got a bearing on the sun in AM... When they say take a compass with you, they mean use your compass and leave the gps in the car!!!
Summary: I purchased a Cobra GPS 500 unit to upgrade from my base model Garmin Etrex. I had thought the 18 channels and FAST circuitry would make it operate better then my Etrex. I was sadly disappointed. The Cobra will not hold satellite lock in any kind of cover at all.
