I just came by this product at Best Buy called I Simple. I was looking at the Dice unit, but this seems to be similar and a bit cheaper. Any thoughts?

The iSimple GateWay - Advanced Car Integration Kit for the iPod and iPhone

 

Since nobody can say anything about this unit one way or another, I'm not risking $$ on it.

 

I don't about the GateWay piece since they don't have any for Audi, but I did find a really cool piece that allows for a clean install to allow you to play music. Best Buy has a piece by iSimple called the ISFM21 that does it by Bluetooth. You don't see the module since there are no wires to the phone, all done wireless with the Bluetooth. I installed it myself in about 45 minutes but I have had my radio out before and knew what to do. Most people can do it in about an hour. No wires to cut and easy to pair with the phone. They have a free app that goes with it, but I haven't used it yet since it worked perfect out of the box.

 

I've had a couple bits of Dice kit and they're very good. I would risk it personally, but I just managed to install the AMI so I'm happy!
