I'm having some issues retrofitting an RNS-D to an A3 8l with a non Bose
I've searched previous posts and quite find the answers I'm looking for. I know about connecting +12v to the SAFE pin but I'm confused about what other connections need to be added / re-routed.
On the attached picture I've circled all the connections the original Concert had. Green shows the connection matches with the RNS-D. Red shows a connection is present but does not match the RNS-D.
I don't have DIS so I don't need to wire a TMC module. (I think)
I've got the following questions:
1) Do I need to connect the CAN-L and CAN-H from the Concert to pins 13 and 26 on connector #4 on the RNS-D
2) What does "DWA-GND" do on the Concert? And does it need to be re-routed?
3) Do I need a feed to GALA on the RNS-D? The Concert has GALA (volume adjusts with speed) but I can't see how the Concert knows what speed it's going.
4) What other connections are required for the 26 pin on the RNS-D
Thanks for reading this far!
