Renault Koleos 2012

[skaiser78]

Hello.

I need help with a Koleos 2012 with TomTom Carminat incl. Joystick w/o Bose.
I bought a Hiworld LNF 1.10 for a Junsun X9 headunit with a wiring harness.
Think the plugs are not pinned right way.
I got a 24pin connector to the old monitor plug that ends at a 16pin plug for the decoder. On the other side there is a 20pin connector ending in a 16pin plug for headunit an also a 8pin for tx/rx. Speaker, 12V all at a quadlock

All help from web says plugin in an setup the junsun.
But I can't get the decoder to work. Only if I make a wired bridge between 12V yellow and ACC red directly at the headunit.
The swc and the joystick don't work.

Has someone a hit or explanation about wiring/colours/pins? I tried out Koleos, Megane and Fluente, everytime I restarted the radio.

Thx for your help.

Take photos of the original head unit's connector pinout and the screen's connector pinout, as well as photos of the labels on the aftermarket wiring harness.
