I'm looking for a new stereo that has USB inputs. Does anyone have experience with these and can offer some suggestions?

I think the Kenwood KDC-MP832U has USB input and is pretty highly rated.

I still have the stock radio in my S... I'm not very informed when it comes to car stereo equipment, so I need some here

 

JVC has several different units. They are just coming out with one that looks like the AVX2, but with a 40GB internal HDD and navigation all in a single DIN HU. You will need an external screen make the best use of it, but it comes with a 3.5" screen on the face already.

There is a thread on this forum dedicated to it. Also, there was a thread on this exact topic about a week ago.... I believe the main options were JVC or the Giga Panel Sony.

Kenwood and JVC both have USB inputs. I put the price next to each one if you'd like to order one from me:

Kenwood KDC-MP632U $223.50
Kenwood KDC-MP532U $157.50
JVC KD-DV6200 $299.00

Don't forget you'll need(well if you want to keep your dash controls) a DCI, and a wiring harness.
If you purchase your headunit from Kinetic I'll solder everything together for you so its very plug and play, 15 minutes install.
