I do agree that it is a bit of a scam, but it's not totally true that it does not do anything. For me it fixed the terrible sounding bass in 5314. The granular volume controls for all of the navigation (Android Auto), Google Assistant, Media etc. is also a very welcome addition.yes I did. It doesn't do any of that. I bought it because android auto has some annoying bugs that I thought it would fix but it didn't. I actually didn't notice any difference. The guy selling it is a total scammer
I am looking into installing this radio into a 2016 Tiguan which currently has a composition color radio, part number 561035150. Do I only just need the ISO Upgrade Radio Adapter FOR VW 2003 To 2015 MQB To PQ?
