The Fuel:
I have to agree with pocket PC idea as I have seen it work. Heck, it will even tell you when you went the wrong way. It says that you have to turn around as you have just gone by your destination. Slick? Pocket PC's with the TOMTOM software will not cost as much as the Chrysler unit, and as mbepic said you can take it with you. And now you have a fully functional PC as a daytimer, web searcher, alarm, recorder, picture viewer, client list, phone numbers and a whole punch more. I have had a pocket PC for years and I couldn't go without it. That's my two cents worth. Good luck?
