Sometimes the touchscreen just shows a Jaguar logo and nothing else (such as steering wheel heat, navigation, audio, reverse camera image, etc). My wife found that if you lock the car using the button on driver's side door handle (not from the remote key fob), 15 minutes later the touch screen works fine. So, we leave the car locked in our own garage. Anyone else expirience this? Is there another solution to the touch screen not working?
