The MK6 generation Golf GTI is one of the funnest daily drivers around with a peppy turbo engine and lightning fast DSG gearbox. This particular car had a touchscreen infotainment system with bluetooth already but it lacked modern connectivity and a backup camera. We thoroughly upgraded the electronics on this 2012 model car so that it'll be great for years to come.
We used a small drill in type backup camera mounted right above the license plate, unfortunately this generation GTI did not get the factory camera mounted behind the motorized VW badge. To facilitate the install we used the iDatalink Maestro RR with VW1 harness. This is the easiest way to manage these newer CANBUS vehicles as it fully retains the factory amp, steering controls, and reads all the NAV outputs. The AX5000 is not a Maestro ready deck so you can't display gauges on it but different models from Alpine, Pioneer, and Kenwood/JVC would support this bonus feature.
The AX5000 is one of the most user friendly head units out there with a very clean design. The touchscreen is fast and responsive and it's one of the cheapest to offer both Android Auto and Apple CarPlay. The compact chassis is great for installing in German vehicles as it leaves room for the Maestro module and the other harnesses. USB inputs allow you to play movies via a thumb drive on the 7" screen.
We also did a window tint on this GTI with Suntek carbon film. We used a 70% on the front and 18% on the rear. This really makes the black hot hatchback look extra sharp in our opinion. The 70% front tint does little in the way of improving privacy but it does help keep cabin temperatures down.
