Can anyone help- i have just bought an 03 range rover- really excited- but- the screen only allows me access to the computer, sat nav (which it says has no disc) although i cannot check as there appears to be no power light to it. There is no display showing Radio or CD (the cd player is there and has discs in it) I think maybe the radio is in fact missing? i have looked in the boot and next to the sat nav box there is one other below it - and quite a few spare cables- can anyone help me identify what is missing so i can get the entertainment stuff working - without a radio/cd i am lost many thanks
