Retrofitting radio controlled clock

[notorious]

I have no answer to that question yet -- need to gather statistics. I fit hormann doors to garage these days so car is not garaged ...

All I know for sure is that radio control mode stays for 3 days even if there is no single signal received for 3 days (and transmitter broadcasts signal continuously). Then the mast will switch off until signal is caught again. AFAIK when mast is displayed again cluster still remembers the delta between CET and UK time, so clock won't jump 1 hour.

Ask Goran who has German car.
