FIAT Talento Visteon 281159932R: Custom Wiring, MediaNav, 32-pin Connector & Steering Controls

Hello!,

I have done custom wiring to change my Fiat Talento radio (same as Trafic III) to use a MediaNav instead of the 1 din VISTEON 281159932R.

I've found information and schematics, including X82 schematics. It works good to turn on and listen on the speakers, but I'm having trouble finding the wiring schematic for the other 32-pin connector. I have a different wiring schematic as it says X82.

I have attached a photo of the 32 pin connector from the van, where you can see, for example, that 18, 31 and 32 are not in use.

It seems that the 6 pins of the control on the steering wheel match the wire color and the scheme, but only Volume Down works.

I don't know what pin #8 is for.

I have doubts about whether pin #17 and #18 correspond to Can HIGH and Can LOW.

And I deduce that #27, #28 and #29 are for the built-in microphone, but I don't know the correspondence for MIC_SIG, MIC_GND and PWR_MIC.

Is there anyone who can kindly tell me what the corresponding pin number on the MediaNav looks like for this atypical wiring?

Thank you very much!.
Best regards.

Hello my friend. Have you figured out how to connect these cables yet? I'm also trying to replace the Visteon with a Trafic navi radio in my Talento... and I've only just figured out how to turn it on. My speakerphone microphone and steering wheel controls don't work. If anything, I'd like some advice. If I figure something out myself, I'll let you know. Have a nice day.
