Hello all enthusiasts. I was wondering if anyone can help me flashing the retrofitted RSE Professional System into my G05 2019. I completed the entire retrofit, the system turns on and everything, but the HU and the RSE do not communicate. I read the faults with ISTA + and now I have a MGU HU error stating that it needs an Ethernet Security Certificate to initiate ethernet. As a consequence the MGU HU, Kombi, and Head Up display do not communicate with each other. I think this is due to me disconnecting the power supply from the MGU HU when I performed the install. I would really appreciate if anyone can chime in, and give me some advice on how to fix my issue.

Thanks

Armando
