Just took delivery of my lovely if rather inefficient Galaxy. There's no books or manuals with it, and I'm jiggered if I can work out how to make things happen. I can make the DVD/CD thingy spin discs and play them, but can't get the audio to the stereo - I have found a manual for t his though, and as Dad is an electrician, he's going to play with it later. More importantly I can't work out how to change the milometer display to give me the mpg, all I can get is well, the miles I've done since I reset it, and the total mileage ever. I've googled, but I'm not too good at finding stuff. Can anyone help?
