Hey Sue:

I went on the Consumer Reports site and found the following...

The 4 top rated:

Garmin nuvi 660 @ $700 Overall rating 83
Garmin 350 @ $500 Overall rating 80
Tom Tom Go 910 @ $500 Overall rating 75
Magellan Crossover GPS @ $500 Overall rating 75

Their "best buys"...

Tom Tom One @ $300 Overall rating 73
Magallen Roadmate 2000 @ $250 Overall rating 70
Garmin Street Pilot c330 @ $300 Overall rating 69

As to the wii, it looks like it comes with all the hardware you need right out of the box. Here\'s a link to the site. As far as games, I have no idea. I'll leave that question up to the gamers on board.

Hope that helps.
