GPS recomendation

[bulls**t]

Im sick of getting lost, so I want to buy a portable GPS for my car. Not the handheld kind, but the kind you can hook on to your dashboard.
Nothing crazy, just good directions, easy to use and input new address, and a car adaptor. Anything beyond that would be great.

Anyone have suggestions? Units sold at best buy would be nice, my little bro works there.
