I purchased a 2014 VM Touareg Lux and quickly felt a need to improve the audio quality of the factory installation. I was a bit apprehensive about messing with this system since it appears heavily integrated with navigation and engine functions, but adding an amp and better speakers seemed achievable. Initially, I worked with Andy. He was very professional and willing to work within my budget. Also, their team was very helpful in answering all of my questions, and were even willing to take pictures of the progress for my own reference and share them on a DropBox account for me to download. Audio Express returned my Touareg ahead of schedule, in time for an important trip to D.C., in clean condition, and with drastically improved sound quality. I expect to seek further consultation on a phase II install where I may choose to add a mobile media center, custom bass, 4" speakers, and possibly an equalizer.
