can you please explain how you got the GPS synchronize the time?

[CODE]
GPS_UHR
aktiv
[CODE]
?

I have done this and was expected that the time will be pulled from GPS module and inserted into the car's computer.

But the time in the car is still not set after driving with this option active for some time already.

My understanding was that once I activate this option, I no longer have to set time and date every time I reconnect my battery...am I wrong in my assumptions?
