I too am having problems with the adaptor. My iphone keeps "chirping" or rebooting. Initially thought the adaptor was not making full contact with the connector, but after trying to push it firmly into arm rest connector I believe it is appropriately positioned (the back of the adaptor is not fully flush with arm rest, as shown by NC's picture).
One time it did work, and the phone did not keep restarting. But since then I've had no luck. I suspect the adaptor is faulty.
Raddoc, I like the content on your idrive screen, but I find it hard to believe you're retaining much about slap lesions while doing power slides in your 1M.
