Nuvi 205 is doing great with me... cheap, easy to use and good looking. oh and yes, for installation, its little suction cup can fit on the wood next to the gear stick without having to permanently damage your dash board (but it won't be in sight, a bit annoying to drive and look if you are totally lost...) and the power cable can run in the groove on the side of the trani housing, and go to the 12V outlet hidden deep in the passenger footwell...

Garmin Nuvi 350 has saved my butt on multiple occasions in multiple towns where I didn't know how to get from here to there.

I used a rented Hertz car with a Magellan system in it last week, and was sorely unimpressed. Just for fun, I asked it to direct me to the closest hospital, that I could see 5 blocks away. It suggested driving 45 miles away. :)
