I'm looking into buying a GPS navigational device like a Garmin or TomTom or etc... Does anyone have any experience with these or know of any good sites with reviews of them? I'm basically looking for: * Large screen * Touch screen support * Talks * Voice recognition (do they even make this feature?) * GPS built in I don't care to view pictures and listen to MP3s and all that other useless crap. Any help would be appreciated.
