Hi:
I just found out the rev/fwd... etc bottons on my OEM unit will not light up when I play CD. I will replace the original "CN541" with "CN538--found on infiniti G20". I will use the "scosche" adapter found in crutchfield to connect the new head unit to the speakers. I will let you know how it goes. The follwing are great links for J30 audio stuff.
