I have a Problem with my Navigation Display; when turning off the engine and removing the key my Navigation System does not Switch off. After one night in the Garage the battery is empty; the DVD Player in the trunk gets fairly hot. - Before this happened, the Navigation System could not find the correct Position anymore, but that was nothing new to me; normally it went back to the correct Position when switching the engine off for 30 seconds and restarting; but this time not - it just refused to Switch off completely. My JAG is now sitting in the contractual Workshop in Hamburg for more than a month; they Claim, they cannot find the mistake. But they also do not dispose of the correct Software for an S-type manufactured 2004 any longer. So they cannot read-out any mistake. - Did anyone ever had a similar Problem and could possibly help? And: Where to get the correct Software for my car? RGDS
