I know of someone whose GXR2 is failing and they need a replacement of some kind. The easy way to do this might be to just find a replacement as long as they can find someone to clone the program, but since the speaker wires are connected at the head end, options are available.
I never installed this system- do the speaker wires pass through the same box as the control pads?
My mechanic told me, "I couldn't repair your brakes, so I made your horn louder."
