If these are important, the 705 is a good option. In my opinion the 205 and 305 aren't worth anything; what's the point of a GPS without maps?
The Edge 705 with the NA Map SD card is great off the bike. We use it all the time for navigating in the car both locally and cross country on vacation. Batteries last about 12 hours, but we have a mini USB charger for the car, so we can run it non-stop.
