Thanks for the advice, I'd worked out the aux connection in the glove box but what did you use for the usb feed? I'm assuming it's only used for charging phones etc and has no connection to the stereo?
Aux feed taken from glovebox to switch then once switch has power you can use for 2 things .
one is a 3.5mm jack pin is for ipod or phone connection for music if you have on phone or from internet via phone data .once you select aux on your radio. The other is usb charger. I used a female usb to male connected to usb pin coming from the switch, which then goes into usb 12v power outlet adapter in 12v power feed behind cig lighter or elsewhere.
