"The best ultra lite unit"2.0 starson
Summary: If you need to carry it around with you this is probably the best out there. The display is necessarily small with the inherant readability problems but useable if you have the time to stare at it a bit. Someone wrote earlier that it took 2 hours to download 8 meg of maps to it. My experience is that serial downloads are quite fast, a minute or two and therefore believe that he has a serial port problem.
