For Porsche PCM3.0&3.1 System（TAX FREE）

Well documented , very good instructions

It's a great system but I wish I didn't have to hit some buttons to get to connect rather connect automatically.

My car is now like brand new from the dealer, greatly refreshed. Module works perfect: Android Audio navigates without any hiccup, Spotify plays all songs even if ask voice assistant to shuffle Laikike1 discography. Audio quality is superb over BT and yes I am amateur audiophile. All driving wheel buttons works ok - however I miss option to fast forward particular song - maybe it can be added in new release of firmware. Highly recommended, best mod for my Lexus

For Land Rover /Jaguar with Bosch or Harman Headunit 2012-2018

It worked perfectly. All the instruction were easy to follow and installed.
