Audi RNS-E LED version G unable to code to 4B platform, please help
I have a navigation plus rns e unit later version G with led lcd. I was going to fitt it in to my allroad 2003, but stuck with vagcom coding. Originaly this is an audi A3 unit (020xxxx). Vagcom lets me to change coding to the A4 B6 (030xxxx) or revert it back, but when I try to code it to 4B platform (050xxxx) it says Coding Request is out of Range, Error 31 and comes back to previous coding.
Additionaly I havent done any wiring to the instrument cluster. Shell I do that first? Any help would be apreciated.
