GPS / Navigation Device

I need to buy a GPS / Navigation device since I'm going on a car trip across country and want to make sure I don't get fucked around with bad directions. My mom recommended a Magellin brand GPS. You guys have any recommendations for me?

Jam it back in, in the dark.

I actually ended up buying a Magellan Maestro 4250. My mother recommended the brand, and Consumer Reports gave this model good scores in the areas that mattered the most to me (accuracy, speed, price, etc.).

It worked great for the trip and got us to our destinations without ever having to pull out a map. The only setbacks were that it seems to have GPS calculation delays when around tall buildings (like downtown Pittsburgh or Chicago), and the traffic re-routing/detour feature sometimes just gets screwy (you have to use your own judgement here). So, it's not without problems, but it worked fine for what I needed it for, and continues to do everything I need here in California.

The accessories are kinda cheaply made though. A couple already broke and I'm going to have them replaced under the warranty.

There's nowhere I can't reach.
