Hello everyone!
I want to replace the current radio with a 3.8" display with an 8" one without NAVI.
I have the schematics of the two radio models and from what I read in this forum I understood that I have to reverse some pins. (USB, acc...etc.)

As the plugs of the two radios are different, I think I will need the following additional products:
1. 18p-24p Female connector (

2. 35p-38p male connector (
Aliexpress link)
3. USB Interface Cable (
Aliexpress link)
4. Antenna with FAKRA Interface (
Aliexpress link)
5. Cables + pins
After studying the schemes above, I have the following concerns for which I hope to find answers from you:
1. ILL +/- (A8 & A17 on 3.8" jack) is Illumination +/- (B6 & B19 on 8")?
2. The 18p-24p plug has a single pin each for Battery "+" (B12) and Battery "–" (B24), and the 35p-38p plug has Battery "+" (B10 & B11) and Battery "–" (B12 & B13). How to proceed in this situation?
3. What is the DETECT pin (A9 on 3.8" plug) and why does it not have a counterpart on the 8" plug?
4. What is MM CAN (B7 & B20 on 8" plug) and can the conversion be done without these cables?
At the end, I apologize for my English and I hope I made myself understood as much as possible!
