I spoke to a distributor of the Match DSP and he wasn't 100% certain what stock system the 2016 Touareg had. He wasn't sure if the "brains" were in the CD player or rear panel. So you've answered this. His next issue was how the DSP would connect if it was in the rear panel. Can you describe how exactly it's wired into the existing system in this case?The radio's "brains" are in the back of the car and the Match 62DSP connects there (not up front like the install video shows), so it does not make sense to install it anywhere in the dash. There is a place right next to the "brain box" where it can mount, but I just cut a bit of the foam that surrounds the spare tire, and installed the DSP unit there so I can access it to load an SD card or plug in USB for programming.
