OK, here's the kast ibus message:
11/5/2008 1:16:45 PM: EWS --> GLO : Immobiliser status: No_key_detected Vehicle_immobilised

At around 1:17:45 the nav should have gone to sleep - did it?

From 1:26:01 is when you did something again, my guess is you opened the boot

Try the same again, with the boot open. Observe the red LED on the nav, it should go out 60s after the ibus activity stops.
