Portable Navigation = Any good?

[inspector_yoo]

Hi. I have managed to save up about 800 dollars, and was thinking about getting a portable navigation system for my car because I did not get the navigation option.

Does anyone know if portable navigation systems are any good? What are the goods, and bads?

I was just thinking about going to Circuit City or something, and keeping it simple. Budget is around 800 dollars (don't forget tax and warranty).

Any recommendations?

Thanks guys.

I got the Acer n35 which is actually a PDA with a built in GPS antenna and love it. I went that route because I get the full-color moving map navigation plus a full-function PDA. Get a big SD card and you can use it as an mp3 player in the car, too.

It's a different route than the other portable nav systems, but I love it.
