OK, As well as battery issues there may be more going on here. Though if you're having gauge sweep then it's on the way and it WILL fail or cause tough start problems in worse weather. I changed my battery and no dash sweeps at all now. Anyway, I've had at least 2 people come to be with this problem now on their GV factory fit radio and both times it was the same fault. Somebody in the past had put in an after-market stereo, or a bluetooth hands free kit, and when they sold the car, put the stock radio back in, or remote the phone kit and didn't bother to pay attention to the wiring they put back in. OK, that eliminates the BCM itself losing the settings due to the memory seat/radio/functions that QinteQ mentions (related to the IOD fuse). So, this is the key question: After driving home. When you get to your driveway. Turn the key OFF and take it out. DO NOT open a door and DO NOT re-insert the key Is the radio still on? These cars have a timer where when you remove key it will leave the radio on for a couple of minutes OR until a door is opened. If the wiring harness for the radio has been mixed up by an after market fitter or similar the two power and ignition wires often get swapped by mistake and so the radio will turn off the moment the key is turned to the off position. See what you get on that one, if it goes off immediately then it's the wiring behind the radio at fault, so take the dashboard facia apart and take a look at the wiring connector into the back of the radio, my guess is you'll see some black electricians tape or some re-wired connections back there as tell-tale signs. Don't forget to post back on what you test and observe as it helps us help you diagnose and also helps others in the future.
