BT Pin out - all pins list
... and on the same subject, I cannot find a list of what all the pins do - there's a partial, and apparently slightly ambigous list in 'Schematics' that covers just the pins required for a non-cradle BT install, and another that is the cross reference to a telematics installation. Does some kind person have the full definitive listing they could make available, and if schematics is wrong (pins 11 and 12 reversed?) , could the author generously update it when they have the time so we have a known good reference source on the forum?
Is there a short between pins 53 and 54, does it matter, or is that now a defective unit?
