For Audi A8

Easy as making chips you peel the potatoes and put them in oil.
You take the road top out the box drop
the glove compartment insert the wires and close the glove compartment back up, hardest thing was taking the screws out.
I done it all myself 😁😁

Perfect

I bought the A4 interface because it didn't require any modifications to the built-in screen or much disassembly. The install was pretty simple, but shoving everything back in the dash was annoying. Unfortunately there is nothing you can do about it because Audi decided to leave barely any cable for the optical line.
I love the option to use the built-in Bluetooth connection my car has. The phone connects to the MMI for calls and sound, but outputs display on the interface. I was hoping this would work like that and it is by far the best feature in there and barely mentioned. No faffing about with AUX or audio call issues, the GALA function works and the screen shows my carplay. Just perfect! The only gripe I have is that there is no way to see the current volume on screen. If there was any way to keep that it would be even better.

Fantastic company with an excellent product. Highly recommended

I own a 2015 Audi a4 that’s in great condition except that its technology is rapidly becoming outdated. CarPlay was not yet available for my model but I really wanted the seamless integration it provides with my iphone. The module was exactly what I was looking for. Installation was tricky but I found some YouTube videos that walked me through the process. Everything works as advertised. My only minor complete is that the music volume using CarPlay is significantly lower than when I use the car’s built-in MMMI.
