2006 E90 12V when key in
Hi,
I'm trying to find a 12v source for my bluetooth adapter that turns on when I insert the key. The cig lighter only turns on when ignition is on, but I need it to turn on just when the stereo is on or when the key is in. I have tested most of the fuses on the fuse box but most of them are always on.
Is there any 12v source which is only on when the key is in?
Thanks
