I've gotten the BNS out and all of the RNS-E functions are working well. As I'm lucky enough to have the SAT harness in the trunk with the SAT antennas already, I'll be buying a 'D' version Sirius model shortly which I expect to be Plug 'n Play (I think I'll just have to plug in & enable with VAGCOM). Once that is complete, I'll be focusing on integrating an OEM BT module and either a PhatNoise box or CD Changer. I'm starting to research the wiring for these accessories and could use a little help. It is my understanding that all of the wiring that I'll need for the BT module should already be present at the factory connectors that were attached to the BNS nav cd-drive that was installed in my trunk. I'm also curious if the wiring I'll need for a PhatNoise or CD-Changer is located here as well? Fortunately, the old BNS drive has a sticker on the top describing the pinouts (just like the RNSE does) although, it doesn't indicate which is pin 1. Here's what it has listed: Connector A (8pin) 1: RFLS (Reverse) 2: GALA (Speed) 3: KL 15 (???) 4: K-BUS (Kline??) 5: No pin (unused) 6: No pin (unused) 7. GND (ground) 8. U8+ (?? Unswitched 12VDC+??) Connector B (8pin) This connector doesn't actually exist, but it's listed on the BNS sticker and shows all 8 pins as 'IC' which means no connector. Connector C (20pin) 1. D CAN_H (???) 2. RB CAN_H (???) 3. RB CAN w/ GND symbol (???) 4. D CAN_L (???) 5. RB CAN_L (???) 6. D CAN w/ GND symbol (???) 7. IC (no pin) 8. IC (no pin) 9. IC (no pin) 10. IC (no pin) 11. IC (no pin) 12. IC (no pin) 13. Mute Out (???) 14. FAW+ (???) 15. FAW- (???) 16. Tel Mute (Telephone Mute) 17. Tel+ 18. Tel w/ GND symbol (???) 19. Tel- 20. IC (no pin) Connector D (10pin) Similar to connector B, this harness doesn't exist in my car. All pins labeled as IC on sticker Any insight or clarification on the function/description of each wire would be extremely helpful. I'm pretty good at digging around and searching, but it's much easier I know what wiring I've got in place so I know what to look for. I'm pretty sure that all of the wiring I'll need for Bluetooth is already there (once I figure out the function of each wire), but not at all sure about PhatNoise/CD Changer. Thanks!
