Difficult to install mainly because Minis are just a pain in the @ss to work on but it all went in smoothly overall. The unit has so many different functions and seems to work great so far. I’m very happy with the unit and functions. A HUGE improvement over the factory equipment.

I was nervous about paying so much money for a unit from a website I didn’t know much about. The original canbus wasn’t compatible with my vehicle however, Khan walked me through how to wire and test the radio. I am now awaiting a new canbus to install. Customer service was FANTASTIC. When I had issues, the responses were within five minutes and was EXTREMELY helpful. Any other company would have given up or took forever to response. If you’re thinking about it, JUST DO IT. You won’t regret it!

Android / BMW install
Quick response from Khan to questions regarding Android system for BMW Z4. System arrived well boxed and secure and able to track delivery. Install took only a morning to install. Large touch screen gives clear images along with SatNav, USB drive and Apple CarPlay & Bluetooth. Good service and good product.
