Interesting, AudiUSAparts shows it at $254 and they sell it for $241.

Curious if there was anything else to it.
Have read/heard that there is some kind of SD card that goes with it and authorizes the update.

Edit: Did you check your DVD drive for it?
This all has me very curious since I don't know just how it's updated on D4.

Checked the DVD drive first thing, but the audio CD I had in ejected . . . Hhmmm.

Do you have the changer in the glovebox too ?

No. I assume that would be in the upper left where I store now my Audi folder.
I had to walk out to the car and check, ashamed to say.

Ashamed to say I didn't even know it was there until two weeks after buying mine...
Went to check the A/C knob/function in the glovebox I read about and found it.
