I had Best Buy do my install on my X3. Although they needed to consult with Tom a couple of times (and Tom G. was gracious enough to assist them), they were gentle with the vehicle.

When I bought the Ice>link Best Buy had a promotion with free installation included. I was uneasy about using them so I first took it to one of our premier car installers in Toronto to check on the connections that I have (the X3 needs a special adapter sometimes!). They couldn't even find the connections buried under the console even though I told them to look there. My car was in at the BMW dealer who confirmed where the connections were. And I decided, if the best stereo installers in town can't even find the connections, they don't have special installation skills on this product.
