Except when dealing with audiocontrol for discontinued products... I have been trying to locate the dashboard remote to the esp-2 for a few weeks now. All Audiocontrol says so far is that it is a proprietary remote no longer being produced. I, inturn asked for a schematic. Since I am a Motorola radio technician with a background in car audio, I figured I'm up for the task. If anyone has one of these remotes to reverse engineer or even a schematic, I would be grateful...
