Hi to Bob and Jim,

Thanks. I will try an external 12v DC power supply to see if that helps. I'll report om the results, maybe this weekend.

With regard to the AUX plug itself, I have plugged my old Pioneer radio (Super Tuner III-D, which has MUCH better audio on FM than the Prius factory unit) into that same AUX plug with no problem, so probably the plug assembly itself is ok. Also I checked the grounds with my old ohm meter and it checked out normal.
