My 2017 GTI has BSM but visual only. My Mazda CX5 had visual (same fast flash with turn signal and vehicle in blind spot), but also had an audible alert that would beep (only with turn signal on and car in blind spot). Not sure if 2018 is same.
Would it be possible to wire in some kind of audible alert into the GTI BSM similar to Mazda one? Thx for any suggestions
