We really should ask Datadatum about price since I think he has it. He has been posting in the thread on AZ that I have been reading.

From what I have seen it is like $2K to $3K for the updated RSNE plus all the cables and stuff to make it work with a B6 S4. Then between $500 to $1K for the back up camera.
The newer RSNE shows traffic info from TMC and I would want the back up camera since I don’t use my mechanical lock on the trunk lid anyways. My car has a trunk lid from another car and I never swapped over the locking portion.
It would be nice if there is a way to get the Video In Motion to work with the updated RSNE. I have not found any posts that say that it does.
I am also looking into if you can stream music because it was mentioned in that above thread.
