So ive managed to get sound into the BOSE amp via the line out pins on the RNS D and managed to switch the amp on with the remote wire although the RNS D only feeds a short burst of between 2-2.5v to switch on/off ive just pumped 12v accessory down it and all seems ok futher investigation is needed I think I may have to change this as it might be causing the following issue.
I have massive amounts of ground loop noise more than ive ever experienced before and ive been doing car audio for many years now.
It only kicks in when no music is playing on the nexus, or I change from one app to another etc I find this a bit weird and noticed it would happen to a friends install only when he actually touched his phone screen.
I have no wiring diagrams for the nexus 7 but thanks to this forum and Delboy maybe I can sort the problem out via the car.
The issue only seems to be when charging. so im going to try and ground the USB module to the BOSE amp ground and see if that makes any difference.
Wish me luck!!!
