You can get a Garmin GPSMAP 60CSx wich has autorouting capabilities but is an excellent geocaching unit also. But I wouldn't get it for dedicated vehicle navigation uses as it is a hand held unit with a small screen. I have a NavMan Icn530 for my car and a Garming Etrex Legend for geocaching. For my budget, I love this combo. The Navman was less than $300, has autorouting/re-routing, sd card slot, and large 3.5" color touch screen stylus pen, can search by address.....alot of features dedicated to navigate the streets. The Legend is rather basic but was less than $150 and is perfect for geocaching, especially a newbie like myself. There are a lot of people here with much knowledge, and I'm sure they will chime in soon.
