I just traded my garmin nuvi 680 for a garmin 885T. I've always loved my garmins. I've had one since they first come out. The 885t is by far the best one I've ever used. Turn by turn, route time, detours, trafic reports, posted speed limit on the screen, blue tooth, FM transmiter, jpeg viewer, mp3 player, doppler radar maps, lane assistant and the best new thing, voice reconition. Has a little remote that goes on your steering wheel. You push the button and you can tell it to do anything that their is a button for, directions, yellow pages, phone numbers and your phone book off your phone. 2 gig free internal memory with a micro sd slot. I don't think thiers a better unit on the market for 600 bucks. I always use it for partying, just unhook it from the mount and set it by any stereo and you got all your songs right their.
Plus with its battery
