Hi, bought X3 2 weeks ago. Yesterday I went to dealer to buy a rear view mirror with a compass buillt in. I asked a service tech if mirror needed any special wireing. He said to just remove old mirror, unplug from plug, and install new compass mirror and it will work. I did just that, turned on car and the compass in mirror did not turn on. Any suggestions other than having dealer install. Dealer will charge alot to do this. Thanks
