Currently I have a 2A firmware in my car on a C nav unit and want to update to 2007 nav disc by making the unit to think that I have a US version.

HW H53
HU/NAVI SW version V220057B
Audio SW version - A2220132 - 110505

I followed the instructions on using the 5 files on the 1A disc and modify the following :

Index.txt
SOFIDX: 0090 NAVVER:V220033E AUDVER:A2220109

LOADING.KWI
Change V222 to V220

replace V222 to V220, replace 017B with 033E, replace v222 to v220

I put that cd in and nothing happens...so whats wrong now?


So which 5 files do I take from? original 2A or 1A

The process is correct but now you will need to change ST 56 channel 97 to 1 to force the RNS-E to do the update (using a VAG-COM or letting the dealer do this). Right now the SOFIDX on your RNS-E is greater than 0150 which causes the RNS-E to skip the update. Changing channel 97 will force it to do the update. Once it's done insert the 2A or 2007 DVD and it will update again and you will be fine for all future updates.
