Guided installation for Audi S6, S7, RS6 and RS7 (New Single Metal Box)
Make sure your car is turned off. You do not need to unplug your battery.
Here is a youtube video that shows much of what is needed. But this video is to install a different product. Only use this video as a reference to point of how to remove the panels. DO NOT REMOVE the MMI all the way like they do. https://www.youtube.com/watch?v=5II76SFAhlU
Changing from flip up to the optional raised setup (sold separately) or back
Flip up mode
do not remove the hinges from the plastic mount. Use either T3 or T4 bits on the tiny screws
Open your driver side door and remove the trim using the trim removal tool that was provided in your package. It will pop right off very easily.
Remove the bolt pictured here so that you can remove the panel below the steering wheel.
Remove the two bolts on the underside holding the panel below your steering wheel. Then pull the panel off. There are a couple tabs on either side of the steering wheel that will really hold on to it. The couple cars I've done I had to really yank it off, nothing broke, but be careful once it comes undone to disconnect the headlights switch otherwise you run the risk of breaking that wire. Once you have this panel removed set it aside.
Remove the climate controls using the trim removal tool provided by inserting it on each side and gently pulling until you hear/feel it click out. You will need to disconnect each of those connectors by pulling the tab up and then removing the connector.
Pro Tip: put a towel down so you don't accidentally scratch your interior.
Remove the bolt that you can now access through the space where the climate control was that holds the MMI DVD unit above in.
Slide the MMI DVD unit out only a couple inches.
run both the flat cables as shown.
Connect the other end of the flat cable now to the port on the end of the box according the photo
Find a suitable place under your dash to securely mount the both with zip ties or tape.
Plug in the power cord into the power port as shown on the image above.
Run the other end of the power cord (red) as shown to the fuse panel. You'll remove the second fuse from the top which is the fuel pump and place the fuse you just removed into the empty fuse slot on the provided splitter. Now plug the fuse splitter into the fuel pump fuse as shown. This is the only fuse I'm aware of here that is a switched fuse. So make sure to use this one. Then find a place to attach the black ground wire to. Suitable places are usually any metal bolt that is connected to a metal frame of sorts.
Optionally, plug in the provided USB extension cord to one of the blue USB connectors and run the other end to somewhere you can access after driving to download your logs to the provided USB stick.
Test, when you turn on your car ignition, your bTres should come on after 30-60 seconds. If it comes on, you are likely done and ready to put everything back and move to the next step. You may have some codes that you'll need to reset using bTres or ds1 web interface afterwards.
Once you have pushed your MMI unit back into place and put the bolt back, you can install the display mount. It's as easy as pushing the extra cable slack back over the MMI unit and then push the slot on the back of the display mount into the MMI DVD slot. There will be some resistance, just push evenly across the display from the sides. Once it's all the way in it will sit very snug. You can pull it back out just as easily in the future if needed.
