act of god

I am in need of some in-car navigation. I have an X50-mid so I figure this would be the best (and cost effective) way to get it. I ran a search and read a ton of stuff, but I'm still not sure which brand/model to get.

What's important to me....well, I live in NY (Long Island) and I pretty much do all my driving between NJ and NY. I don't go cross country or anything like that. I do hit a lot of traffic and I'd love to circumvent if possible with a little help!

I suck at directions, so something that has a good user interface is important. Plus, I'd like it to look nice. haha.

Not really sure about the differences between BT and CF besides cord/no cord.

what ya got for me?
