Im wanting to put a 12v to usb adaptor into the car to power a bluetooth receiver, I want it to be on when the radio is on so looking for a 12v output from the radio when its turned on, possibly a signal to an amp, CD changer or electric arial sort of thing. Anybody aware of such an output ?
TIA
 
You are better wiring it to an accessory switched feed, as if it only comes on with the radio, by the time it's booted up the receiver and that has connected to your phone, the caller will have probably hung up! At least doing it the way I suggest, your phone will be paired to the reciever all of the time, and if it's off, turning the radio on will get you the call/music straight away.

Accessory live was my first thought but think a radio live would be beneficial so I could switch off the radio and break the bluetooth to the phone. Anyone have a diagram of the pinouts?
