RNS-D coding (especially for Bose)

[HPsauce]

Hmm, went and plugged in VCDS and looked at the Soft Coding field in both the Radio and Navigation controllers.

Radio said something like 1740, no idea what that means.
Nav said something like "Inv. Msg. Len."

I'll check again tomorrow, maybe that's a communication problem?

I have RNS-D with Bose, let me dig out the coding from a scan. The coding is extracted from the unit I got from Ranj, I have not altered it since the car it was removed from had Bose.

Address 37: Navigation
Part No: 4D0 035 192 M
Component: RNS 4.2 H06 BNO 0140
VCID: 295DF997F969

Address 56: Radio
Part No: 4D0 035 192 M
Component: Radio BNO 0001
Coding: 00017
Shop #: WSC 00976
VCID: 295DF997F969

Thanks, my car is non-Bose and looking at some saved scans I can see that the Radio was generally 00207 (since I got the car) though I have one scan of 00117 though I'm not 100% sure what unit that was.

Anyone know what those codes mean?

My memory may be faulty, that was probably 00117.

I dont know if this thread helps.

Thanks for that, will have a look sometime (unless someone here already has that info).
Meanwhile I just changed 00117 to 00207 and the front speakers burst into life.

OK, I've got the coding table, here's a sort of interpretation:

Radio soft code is 5 digits, all are binary values from 0 to 7.
The three options within each field are valued at 1, 2 or 4 (for on) and are added to give the value. Standard binary stuff.

First digit = 0
Second digit = 0 for A8 or Bose (Sound curve, uses other values for other models without Bose, e.g. A6-C5 is 2)
3rd digit = FaderOff(1), BoseDisplay(2), ActiveAmpPhoneDeactivate(4)
4th digit = Navigation(1), Telephone(2), VCS(4)
5th digit = DiversityBox(1), CDchanger(2), MFSW(4)

Not sure that makes sense of my 00117 and 00207 codes though.

Be aware that USA coding seems to be nowhere near the same as Europe. I found coding values quoted for our A6 that were completely off the wall compared to what it should be!

I read the code off the A6 stereo to know what to change it for, but when I got in to the soft code entering page it came up with a guided list of each number to enter which tallied with what I had from the old one

That's for a Bose system without telephone.
