Hey I have recently fitted a RNS-E 8PO 035 192S. Previously I had the concert. Now I've had it a few days I think the concert sounded better - we have swapped the bose brown wire from pin 5 to 7. We didn't check the volume characteristics (Adaptation 8?) as they are not listed in the on-line Ross Tech Wiki. Does anyone know the list of options? Do they affect sound quality? I have seen code 255 mentioned elsewhere for Bose, is this correct? I can't see any GALA settings available on the unit which might suggest it is already coded for Bose or it's on '0' disabled setting. When swapping the brown wire on my car's loom pin 7 had a grey 'k-line' wire. I assume this is redundant but we put it back in pin 5. Would this cause any problems?
