Alpine head units have an antena motor wire and work fine with BMW power aerials. Masts jam alot. Changing is easy, as above. Radio fitters and alarm/imob installers are loom wreckers with black tape. ID the wire by colour code at the ends - it does not change.
SI batteries; gears and the little capacitors on the logic board (if the batteries have not burst and buggered the PC board). I saw changing them on another forum - fairly easy.
Fix that lot and I think the dash will work fine.
Good - Fast - Cheap: Pick any two.
