The Magellan I have for the car, Maestro 4040 is a bulkier unit, the trick would be to mount it too. But for the money, well under $ 100. Their 4350 is $ 70 on ebay, has bluetooth, so your phone can sync to it and you can use it for that also. 4350 has 4 hour battery operation. The 4040 I have goes only 2 hours on battery. That's ok though, really only want to get an idea of where the route is rather than leave it on and be directed doorstep to doorstep. In that case it can go into a backpack and be used as necessary, saving the battery for critical use only.
