If I remember right, I have mine connected to the driver side reverse light wire so it only activates when reversing (called the trigger wire I think). There should be another wire for power, then the RCA to the camera. Up front, you should have an RCA to connect to the unit, then another wire to connect to one that should say "Reverse" on it. I would rig up the connections and test before soldering, etc.Thanks for the help! Any thoughts on where is a good spot to attach the red wire to pickup the reverse signal??
I too have a mic with a mini-jack hookup but, as soon as I plug it in, it doesn't work. Unplug it and the built-in mic activates (and works). But people tell me I dont sound very good. Im hoping to get the external mic working...not sure if it needs to be turned-on somehow.
As to the mic, I think there is a setting to "activate" it. It may have been already set from the factory for me, but not on yours. I'll take a look to see if it exists or not.
