Hi, I have the same problem as the OP - when streaming music from my phone to the Bolero bluetooth - the left channel is missing, it seems the right channel is going to all speakers. As a workaround I have a bluetooth receiver dongle thingy plugged to an AUX port in the armrest. I stream music from my phone to that and everything is in wonderful stereo but of course I need my phone out to play/pause/skip etc, so not ideal.

langers2k, trying to match your diagram with my pic if the 4 wired pins on the green block are the 5, 6, 11 and 12 you speak of then missing wires are not my problem (sigh)

Ok I have a facelift model from '14 so maybe different scenario. Here's the back of the unit - what am I looking at/for here?

I have this exact problem too! I have connected a bluetooth receiver to the AUX port but fixing the head would be a much better solution so yes please to more info.
