Hi all,
I want to install a bluetooth adapter to the accessory port of my 2005 Mazda5 head unit and run into a problem: I can't get it to work on the ACC power pin of the head unit, while it works perfectly on the B+ power pin. (But it then stays powered all the time, which I don't want to prevent the battery from draining)
The schema I used to install the adapter is this one:
I have a 12V to 5V power-converter to power the bluetooth adapter. When I connect this adapter to pins 2A and 2P, it works fine.
But when I connect it to 2A and 2O (which I assume is a switched 12V output), the power converter does not work: it outputs about 1V instead of 5V.
Any help would be greatly appreciated!
Stefan.
