Started my Jag and got this on the touch screen display. Buttons on side seem to work but of course I can't see anything. Any way I can resolve this?

 

 

Could you walk me through that?...

 

 

Thank you! Yes, battery at full charge. I let the car sit for awhile and double locked it....when I went back, the screen had returned to normal function. Being that this is the first time this has occurred in driving the car for a year and a half, it's possible that this is a symptom of things to come. I will keep your instructions on file for possible future occurrences:-) Thank you all for taking the time to help me out!! Happy Hollidays.

Seems like it's a classic graphics card issue seen on computer screens too.

 

Your car is still under warranty, so take it back and they should replce the unit.

If it were me, I would remove the head unit, and I bet it's the ribbon cable and very fine pitch connector that connects the PCB to the screen has a partial connection.
Just a wiggle first would most probably suffice, if not delve deeper.

Dealers will just chuck the old unit in the skip I guess...cheaper than fault finding these days!

 

 

Disconnecting the battery and touching the leads together discharges any current remaining in modules (capacitors) and in theory resets, the screen in this case. Jaguar recommends this on a few of their TSB's. If it doesn't work, no harm done. For those in Europe, you might want to save your radio code so you can re-enter it if needed. No code required here in the U.S.

 

With a lot of radios, unless it sees a VIN change, no code entry is required.
