Installed a Euro RNS-E in my 02 A4, music functions work great, sound is awesome however I am stumped on converting from Euro Firmware to US Firmware.

I have read every thread I can find on creating the firmware update disk, I purchased the VCDS from ross-tech to set parameter 97 to 1, still can't get the RNS-E to update the firmware

When I enter Engineering mode, my settings are as follows

System SW Index: X---
HW Index: H76
Map Database Index:
HU/Navi SW version V2200815
Boot Version V220100D
Audio SW version A2210141-080807

I understand that it is running in some type of hybrid mode

I have tried creating update disks using naviedit.de's VIM tool, I have tried using a hex editor to edit loading.kwi, I have tried changing the sofdix to increase by 10 / 20 / 100, nothing seems to make a difference, I have D/L'd the 2009 NA Map, the 2010 NA Map and all the disks ever say is "Software update" with the corresponding sofdix from the index.txt file

I have created more coasters this week than I have in the last 20 years

I thought it might have been the burner I was using so I purchased a new Liteon 324, no difference

I am ready to give in and purchase the latest navteq 2010 Disk, but before I drop another $200 into this project I need to know that it is going to work.

Hopefully someone can give me some guidance to create the update cd

Thanks in advance,

 

have you checked audiforum.us these guys know pretty much all there is to know about the rnse.
i have the 07 maps in mine i know if you upgrade to the 2010 maps from navteq it disables all video inputs, thats why i am still on 07 as i have tv/dvd/ and reverse camera and dont want to lose these

good luck
