Okay, I’ve been sitting on this project too long and if I was going to be the “pioneer†for this then I should have done something with this info 2 months ago. Here’s the parts list:
Lambo CAM ECU: 400 907 441 : $550 from Lambo
-OR-
VW CAM ECU: 7L6 907 441: $300 from VW
Lambo/VW Camera: 7L6 980 551: $180 from VW, $390 from Lambo
The thing I am waiting on is the wiring diagram for the Touareg so I can see how the CAM ECU is connected to the nav unit. I do know that the Lambo ECU uses a 16 pin connector and the VW ECU uses an 18-pin connector, so I assume that the connections may be different. The camera is connected to the ECU with a 6-pin connector. This connector carries signals for the video and +6V power to the camera unit. The Lambo ECU activates the camera in two different ways. First, if it gets +12V on the Reverse wire, it activates the camera indefinitely (as long as the +12V is active on the reverse wire). Second, if it gets a momentary ground signal on the “Switch Camera†pin, then it activates the camera for about 10-15 seconds then switches back off. The ECU sends this signal to the RNS-E to the RFSL pin C2. This is why I have stated that the coding of the RNS-E will most likely have to be for Lamborghini in order for the camera input to be activated simply by sending power to pin C2. You’ll also notice that the 16-pin connector also has connections for the camera but it uses the 6-pin connector for those.
Pinouts for the Lambo CAM ECU:
584A (6-pin connector)
1: Vid In from camera
2: Vid shielding GND
3: GND to Camera
4: +6V to Camera
584 (16-pin connector)
1: Kl.30
2. Kl.31
3. RFS (+12V input from reverse)
4. Enable RNS-E (to pin C2 on RNS-E)
5. Switch Camera On (momentary ground input for 10-second activation)
6. GND to Camera (not used in Lambo)
7. +6V Camera (not used in Lambo)
8. Video Out-R (to RNS-E T32/32)
9. Video Out-G (to RNS-E T32/16)
10. Video Out-B (to RNS-E T32/31)
11. Video Out-Sync (to RNS-E T32/15)
12. Common Video GND Shielding (to RNS-E T32/30)
13. Composite Video out (for use when TV tuner is also installed)
14. Composite Video Shield (ditto)
15. Vid In from camera (not used in Lambo)
16. Vid shielding GND (not used in Lambo)
That’s about all I’ve got for now. I really need to finish my research on the Touareg ECU because it’s bound to work with the RNS-E once you know what the video connections are.
