I have a aftermarket nav unit that I purchased and would like to have it powered on when the car starts. Using the lighter is a bit too many wires for my liking. I have it mounted by the vent on the drivers side left. (works great btw )
Is there a way for me to add another power source...I have never really messed around with the wiring on this car. Not sure if its an easy solution or not but any suggestions would be appreciated.
