This seems more like a G4 hardware or BIOS bug than an SD bug. There are a few people here in Russia (including myself) who are experiencing a similar issue and none of us are using SD.

In my case, this happens every time when I leave the G4 in standby state for more than about 10-12 hours, then it seems to shut down automatically and the clock goes off, way off. If I happen to get back to the car while it is still in standby (that means within 10-12 hours after entering standby), the clock is ok. If I shut down manually instead of entering standby - the clock is ok even if I don't use the car for weeks.

The available manuals vaguely hint that the G4 is suppossed to shut itself down either after some fixed time of inactivity or when the battery voltage falls below certain threshold.

As the exact number of hours after which the little bugger decides to shut itself down screwing the clock in the process seems to vary widely, I tend to believe that we are not dealing with a timeout here but with an overly sensitive voltage sensor. I really don't know what to do about it as I have a brand new car with a brand new stock battery - am I supposed to replace it? Needless to say, I have never experienced any electrical problems with the car - the engine always starts perfectly.
