can't go wrong with Garmin or Magellan. I use an entry level Magellan Maestro 3100 and works great. I don't need all the other features that the more expensive ones offer; the 3100 gets me from point A to B. Good bargain at $100 used ($125 new during Black Friday, $150 current market price). I switch it back and forth between vehicles; it takes about 10 seconds.
