After several years building courage up to do this I finally decided to buy a kit for my XF.
This kit has full integration with the cars audio and as such doesn’t need additional dedicated microphone or aux connections in the arm rest storage.
On the downside it means you have to disassemble the centre console as well as the dashboard so you can access the navigation system and the header unit. If you’re not into car maintenance get someone who is to fit it, this isn’t something a novice should do IMO.
The instructions on how to centre the image in the header unit display are nonexistent use the dip switches marked left and up on the top of the unit.
Otherwise very happy, definitely brings the car into the modern era and It’ll probably add value to or at least make the car more saleable in the future.
