Summary: My first GPS was Nextar. It was very easy to use, had the volume switch on the outside, and had day/night settings. The mounting bracket holds this on the windshield as long as long as you want to leave it there. I haven't been using mine lately and basically it was "kicking" around the car, under the seat, in the dash, etc. The other day, I plugged it in and the screen went to all lines.
Summary: Im just getting started with the Nextar GPS. I have never owned one before but found this one very simple to use. I cant see spending more on a different unit when this unit does everything I need it to. I had no issues so far with it. Charge it 4-8 hours and go.
Summary: Compact, eloquent, lightning speed, no missed opportunities, seems to know all speed zones anywhere, seems to know when red lights change, speed alarm is accurate anywhere, MP3 player is user-friendly and computer savvy, shows slideshows as well as any other player. Voice is pleasant and all directions given in plenty of time for lane switches, etc. I recommend this unit highly. Replacement parts are readily available from a number of aftermarket dealers.
