XKR (X150) control screen not working

[a8hex]

Yesterday the control screen in the centre console of my XKR wouldn't play ball. It just displayed the XKR logo you get when you first enter the car and wouldn't boot up into the normal mode where you can control everything. Stopping the engine and restarting it quickly didn't clear things. After I'd parked up and taken LadyB8 for tea and cakes everything was OK again.
Has anyone else seen this?
Any suggestions of how to get out of it?
The rest of the electronics all seemed to be working, parking sensors, trip computer etc... just no control screen and so no seat warms (LadyB8 not happy ... ... ) etc.

It's normally on a conditioner when in the garage, but I admit it hadn't been last week. I'll pop it back on
Cheers

It's only happened the once for me. When I stopped the engine and parked up for 20 or minutes and tried again everything was OK, a quick stop and start wasn't enough to clear things, but I'm not sure that it would have been long enough to restart the control system anyway.
It's always difficult to troubleshoot things that don't happen predictably. I was wondering whether anyone else had seen the same issue and whether anyone had found a trick to get the system back online.

Thanks
One battery related message the car does give me from time to time is that if I have the radio(etc.) on with the engine switched off after a few minutes it gives me a message that it will shutdown after 3 minutes due to low battery. Its done this ever since I bought the car. The dealer told me I'd need to take the car out for a longer run as the self calibrating system took quite a while to set itself properly. Of course this didn't make any difference :-)

Hmm dealer wasn't really on the ball then, he missed an opportunity to try and sell you a new battery at a healthy markup

Nahhh, I'd only just bought the car from him, so he was ducking the opportunity to buy me a new battery.

Not sure with modern Jags, but I remember with LadyB8's last Merc that it also meant re-programming all the electric windows so they knew where up was.
