Radio installation

Hi,
I have a 2005 X3 and I am installing a Alpine radio in it but am having a little trouble as I do not see any ignition switched 12v supply to tap into anywhere near the radio. Can someone please suggest where I can find this supply.
Thanks

There is a 12V switched right on the radio wiring harness. I strongly suggest getting the proper adapter connector and not cut the wires that way all the proper connections are easy to manage. The adapters are dirt cheap. A BMW wiring adapter is $6.00


Car Radio Battery Constant 12v+ Wire: Red/Green
Car Radio Accessory Switched 12v+ Wire: Violet/White
Car Radio Ground Wire: Brown

I do have the harness. I will check that violet/white wire again. Thanks!

Vehicle coding can be changed to make the ACC/switched line stay on up to 10 minutes after ignition off. Yours might be set that way by the dealer.
