I just installed my unit this evening and I have a volume problem. There is low volume, even though I have the radio volume all the way up. Any suggestions????
Can you use the program button and "change CDs?" Or is it just blinking the CD # and Track #?
I had the same symptoms as you. In addition to it not recognizing the GROM unit anymore (blinking CD and Track #s).
GROM said the unit I sent in was fine, but they sent me a new one that I just received today. It has the same damn problem.
I tried different cables, etc, pulled the radio fuse to "reset"... but nothing. My iPhone was still charging even though the radio fuse was pulled and the radio did not have power. The CD Changer cable obviously has a constant supply of power.
Instead of disconnecting the battery, I pulled the clock fuse. My iPhone stopped charging... so I waited a few seconds, put the fuse back in... and then BOOM, everything is working again.
I hope that helps someone!
