All was good for a while with my install, but now the right channel went to about 1/4th the volume of the left, and there's a tick-tick-tick-tick that plays even if the iPod is paused.
It stopped for a bit after I checked the wires, but today without changing a thing (not even unplugging the iPod) it started again.
Any ideas? It doesn't come via the headphone if I plug them in while it's occurring while the connector is connected to the AVIC and playing.
