I have the updated map disc and everything seems to have power.I have nothing on screen nor does the controls around screen work. Where the temp for climate control flashes 50 then 51 where the outside temp is displayed directly below screen. If the car sets for 48 hours without starting the brand new battery needs jumped. We have checked battery for voltage and it is OK. I'm thinking their may be a draw from the inop nav system. This car has 80000 miles and is like new inside and out. Cars drives out GREAT! PLEASE HELP!!!!!
The outside temp 50-51 is caused by a faulty external temp. sensor. found at the RHS in front/below by radiator under spoiler. it looks like a small plastic sparkplug, cost from dealers about £5-00. This will affect your climate control and not allow it to function correctly.
If your touch screen was working correctly before the update it might be worth trying your old DVD back in the unit for a reboot.
Als0 check in your handbook that your ancillary fuse for these items is okay. If after this you still have no display or action on your screen - it sounds bad news and it might be new screen time, but get it checked first at a good auto electricians .... because Jag main dealers only put in new new new ..... they are not interested in finding problems. Good Luck !
Dealer can do system update of nav unit
