Nav Issues
 

Sometimes when I open my door (03 540 w/V28 OS) the splash screen comes up (normal) and sometimes it takes a few minutes. Any idea why? Can I change just the splash screen after the V28 update?

Depends on boot status of nav unit.

If car is fully owered down and asleep (orange gear-shift light on trans is off), takes longer to boot
If nav was awake, takes shorter

if you use the unlock key from further away, as you walk to the car, you give it more time to boot
