I recently did some research into replacing the dreadful factory nav unit with a custom "carputer" that keeps control over the factory systems over the CAN bus. To my surprise, I came across this interesting video:

The company website doesn't yet list the XF as a supported model, but they clearly have a system that works judging by the video. Anyone willing to send some money to Malaysia and try this out for the rest of us?

 

Seems it desynchronizes the dash vents.....

 

He sure pushed a lot of buttons to get nothing I understood! Video was useless to me.

 

The major issue I have with the current Jaguar navigation system is not the interface, but the lack of response or lag time from screen touches...I wonder if this can be remedied by a future software upgrade or if it is a hardware obstacle.
