Seeking Vehicle Mount for NUVI

I got a Garmin Nuvi for Christmas so I called Pro.Fit and they don't have anything. Does anybody know who makes a mount for those?

Umm...Excuse me! I'll have an iPhone!

The time has come. I broke down and bought an iPhone last night. I have been thinking about it for a few months, but I actually went to the Apple Store last night and got it. I can't believe I've been missing out on this for so long!!!

I know that I haven't had it for very long, but so far I am thoroughly impressed.

I do, however, have a question so if anybody knows please pass it on! How can you hook your iPhone up to your car's radio? Do iPod interfaces work with the iPhone?
