I just picked up omy M3P today. I have a radar detector, but the 12V is too far away for my to hang it from the windshield. I thought there was some USB's near/under the screen, but I can't find any other than the 2 in the back. I don't want to hardwire a detector, and don't want to really take the car apart to run a cable. Isn't there any other way, besides for getting a wireless detector?
