I've posted this response on other threads here cause many people are having this problem: .....I've seen alot of explanations for this prob, as I had it myself. I took my unit out of the dash a couple of times, twisted the RCA connections and it fixed the prob. Catch is, it will happen again. I have the Pioneer cable going to my Nano. Reluctantly, I finally soldered the RCA connections and it's been working flawlessly ever since. It was a major pain, but worth it. You would think Pioneer would do a better job with their cables....... Hopefully the guys who have replaced their cables will be good, sucks pulling the unit out of the dash.

I have been attempting to troubleshoot my problem of losing the left channel on my iPod.

Firstly, I replaced the cable with another Panasonic cable. That worked for about 2 days. Then I found that by disconnectimg and reconnecting the USB cable, the channel would return, for a while.

However, if I use a USB stick plugged into the USB cable, it works flawlessly, the whole time. I reinstalled everything on the iPod (as suggested above), but that made no difference.

Does that mean that my problem is with the iPod connector on my (new) cable? The USB cable itself seems to work fine for everything that isn't an iPod. Does it rule out my problem being with the RCA connectors on the rear of the unit?

ONLY the ipod splits USB and RCA, anything just plugged into USB uses only USB and a bad analog connection would not affect it.

You need to go back and troubleshoot the ipod as everyone suggests, the only thing "USB plays fine" proves is that the amplifier and outputs of the AVIC are working, it does nothing in relation to the analog ipod/USB/dock connector path.

I have had to replace my 900BT (was affected by the ipod issue and some jerk stole the unit - and the problem BTW) recently. The new unit is a 9110BT (the 910BT with VW facia plate) and the problem is gone. Biggest difference with the USB connection compared to the 900: the USB is a long cable permanently attached to the unit (no chassis-female USB connector on the back of the unit anymore).

Could this be Pioneer concluded that the ipod issue is often related to the chassis connector?
