I am opening the post because I am installing a medianav mn3 on my traffic 3 phase 2 which is originally equipped with an r-link evolution.
The r-link evolution is in two parts the radio and the screen separate, the screen is with a 24 pin and the radio is a 32 pin (steering wheel control I think)
Main screen 24p connector r-link evolution
1. CANMH1 --> Multimedia CAN1
2. CANML1 --> Multimedia CAN1
3. Microphone-Supply --> Supply for microphone
4. Microphone-Signal --> Analog microphone signal for voice recognition feature
5. System_On --> ECU wake-up signal
6. Ubat --> Power supply of MFD
7. Ubat-ground --> MFD ground
8. Stereo-Audio-out-L --> Analog stereo left output for multi-media unit audio
sources: Ext. USB audio-source
SD-card audio-source.
Phone (voice & ring) source.
Other from internal MFD.
9. Stereo-Audio-out-R --> Analog stereo right output for multi-media unit audio
sources: - Ext. USB audio-source.
- SD-card audio-source.
- Phone (voice & ring) source.
- Other from internal MFD
10. Stereo-Audio-ground --> Audio output return.
11. Stereo-Audio-shield --> Audio output cable shield.
12. Speed --> Vehicle speed information for navigation function
13. Mono-Audio-out --> Analog mono-audio output
- navigation voice and alerts
- voice recognition.
14. Mono-Audio-ground --> Mono analog output return.
15. Mono-Audio-shield --> Mono analog output shield.
16. Microphone-ground --> Microphone analog out return.
17. NC
18. CVBS-in --> Analog video signal from rear camera.
19. CVBS-ground --> Analog video GND
20. Camera-supply --> Power supply for rear camera.
21. Camera-ground --> Camera supply return
22. NC
23. NC
24. NC
On the screen there are 3 mini USB connectors
gray --> connected to the radio
black --> USB and SD card reader unit
brown --> Telematics Unit

I started transferring the pins from the 24p r-link to a blank 24 pin connector for medianav
Power
5 --> 2 medianav (the medianav goes into standby mode when I turn off the ignition and open the door and turns off when I lock the doors)
CAN
1 --> 15 medianav
2 --> 16 medianav
MIC
3 --> 8 medianav
4 --> 7 medianav
16 --> 19 medianav
CAMERA
18 --> 10 medianav
19 --> 22 medianav
20 --> 9 medianav
21 --> 21 medianav
This is where I am for the moment, the microphone works, eco driving ok, temperature on screen ok, standby time ok, GPS speed ok, but the reversing radar does not work
The problem is that sir my r-link evolution I think that the steering wheel controls and the reversing radars work with the CAN network which arrives at the radio unit
Can you help me find a solution?
Thanks
