Wireless CarPlay Android Auto Retrofit Kit Compatible with 2013-2018 Audi A3/S3, Carplay Module Receiver Box Support Navigation, Maps, Music, Mirroring, Camera

Installed on my 2011 A4 Avant prestige. Easiest install ever, just make sure you order the little key tool separately to remove the MMI unit. Otherwise the install took less than an hour. Instructions were perfect and everything was plug and play. Works seamlessly with the OEM Audi controls on the console and steering wheel. Also very nice to get precise audio EQ control through the unit that Audi doesn't provide from factory.

Overall for the price I’m very satisfied. The interface seems to work well and I’ve been using it for over a month. My only complaint is the instructions were not clear/incorrect in relation to the ribbon cable not needing to be connected prior to testing. The ribbon cable that connects to the buttons does need to be connected prior to the testing stage otherwise the unit will not switch on. Overall very satisfied and I think the price is fair.

Absolutely love this, I got it for my son for his 2016 Audi A3, although Audi has its own screen nothing beats the CarPlay, easy installation and it works perfectly

Installed this in my 2014 Audi A4 B8.5 with 2G MMI. The most difficult part of the install is removing the vent and radio. Make sure you buy trim removal tools and the Audi keys to remove the unit in the glove box. Directions on YouTube don’t have English and are very hard to follow. The unit stopped working after two days. Car play would randomly disconnect and the screen would turn black and go back to the OEM screen. When holding the "NAV" button the module would click and the screen would just flicker and go black. I triple checked everything and nothing is installed incorrectly. The controls never worked for the center control knob and I could only get the steering wheel to control everything.

Worked at first few months then it stopped working completely
