New here. Have been searching dilligently through the Quick Links and FAQ trying to determine the most efficient way to convert my RNS-E to US.
Summary: purchased a supposedly US RNS-E on eBay. Seller listed item location as Maryland. Two days later a big DHL box from a Baltic country arrived with an RNS-E and wiring harnesses.
I installed the unit in my 2005 B6 A4 (previously Symphony II w/ Bose) and waited 60 minutes to enter the security code. All seemed well, but when the $199 navigation DVD arrived from NavTeq, the RNS-E said no Nav DVD was inserted. When I open the screen to access the drive, the screen (now in a horizontal position) says there is an update disc inserted. No updates occur.
After reading through this site, it seems both possible and practical to convert what I now know to be an EU RNS-E to US-like spec.
I made some sreen shots in Engineering mode and transferred them to my PC. The results are:
"System SW index: 0460
HW index: H56
HU/Navi SW version V220066F
Boot version V220100D
Audio SW version A2210134-280705"
In non-Engineering mode, the "Version" page displays "SW: 0460"
I mounted the GPS antenna behind the glove compartment under the dash. The Lat/Lon results I saw in Engineering mode were acceptable, so I think that placement works.
I talked to the resident RNS-E expert at a local Audi dealership, and he said that a software update could be performed that would restore normal US functionality. After playing with the actual unit, he seemed less sure and asked me to schedule a subsequent service appointment.
I am going to be using the car for a long-distance road trip in approximately one week, so I am under some pressure to get the system working ASAP.
From what I understand, I can make a CDR of with modified versions of:
And, using a VAG-COM, force my RNS-E to reset its SOFIDX to a lower number. After which, I should be able to insert my 2007 US Nav DVD and have it flash up to current US firmware and maps. Is this correct?
If I am on the right track, in what way do I need to modify the files listed above. I have read conflicting reports as to the appropriate way to modify said files. I have already copied them to my PC, and have downloaded Groovy Hex Editor per the recommendations of other users on this forum.
I have never edited in Hexadecimal before, but believe I can do it if I can find out which entries need to be modified, and what the new values should be.
If anyone is willing to give me some help or advice with this, please respond! I am in over my head with this project.
I have not yet purchased a VAG-COM from Ross-Tech. If responses to my post appear and it looks as though I will be able to successfully modify my RNS-E, I plan on purchasing:
Please let me know if this is not the appropriate VAG-COM for a B6 A4.
