Hi Joel and Gerald,
Yes, this is exactly my intent. I do not know why Beaver didn't wire the radio this way in the first place . All vehicles I have owned, allow use of the radio/cd/navigation system while parked, by switching to the 'auxiliary position.
Gerald, you mention adding a 'solenoid' as the power source for the ignition switch auxiliary position. Could a relay do the job, or better could I just run the radio/cd/nav.system directly to the 'auxiliary' position on the ignition switch ??
