some quick answers (see the quicklinks post in this section for more details):
- looks like you have a digital instrument cluster; so if you have a 2001...then you probably have one that is CAN-enabled. If you buy a D-Navi (CD-based), then you can get Nav/Radio/CD info to the cluster....ONLY if you have a TMC/CAN gateway installed.
- As for illumination etc, the D-Navi (or C-Navi) Nav+ units did not use the CANbus for illumination, ignition etc. It still relies on the analog connections within the existing wiring behind your concert HU..so you are in good shape.
- as for the double-din console....as you know, you will have to do some major work to reshuffle some of those dash components. Sounds like you already have that end of the install covered. Can you get a D-navi unit for an A3 or will you try to modify the faceplate of a C5 A6 unit?
Bottom-line: You should be in good shape to do this install. See the quicklinks for info TMC/CAN gateway, part#'s, etc...etc.
Good luck!!
