Hi, Just bought a 2007 X3 M Sport, lovely car for year and very pleased except,
was told the sat nav just needed a new disc. Bought a set from ebay, has a v32 disc and a BMW map. V32 loaded OK but map disc was refused, 'Please insert correct disc'. The seller said its the right disc, the Sat Nav is in the boot with 'DVD' logo on it. Does anyone know what disc it should be?
Also key fob only works intermittent, could it be the battery in the fob? Its the diamond shape.

Thanks
