Retrofit almost complete! Also decided install a helix sub-woofer
Oddly CarPlay worked but audio doesn't work on everything yet.
You could see in these photo where i had to add length to the harness to make sure it reached.
I emailed eurozonetuning and it turns out they have updated their harness and it includes now the CAN-BUS wires and blue connector wires, They said they would update the listing to include updated photos but as of writing this they haven't. Bill from eurozonetuning emailed a photo of the updated and a little photo sample in case you need to relocate some of the wires on the harness. I would definitely research what wires are needed on your harness as i still think the eurozonetuning harness still needs additional wire for blue connector. I ended up using the harness that i ordered from aliexpress as they finally arrived the day after i ordered the harness from eurozone. i did have to cut into the harness and make the canbus wires and the blue connector wires reach, i used butt connectors to make them reach.

The hardest part was honestly removing the glove box. There weren't enough decent guides that I could find online. One cool thing i found out is that you could replace the lid/door on the glove-box. It just so happened that i bought a golf r glove-box with a damaged lid/door and used the stock one to replace it. Only thing that sucks is if you get the glove-box with the nice inner fabric, that can't be transfer as far as i could tell.
There is two plastic rivets that hold the lid/door in place once you remove the glove-box. You have to essentially push them back through the two holes on each hinge to release the lid/door, I really don't know what tool you could do this effectively with. I used a pair of scissors and two small Flathead screwdrivers. I did a little damage to the rivets but i was able to release the lid and then add the new one.
I am working with Jack hopefully on Monday or Tuesday to get this programmed!
