If your Nav unit is MK IV (MK-4), then I would think that you can get an OEM TV tuner that would go into designated spot, then get a TV tuner harness that goes between the TV tuner and the Nav unit, connect the audio wires to the radio unit, connect two antenna aerials to the TV tuner and - voila!! I have this set up in my X5.
Anybody has done this to an X3? Please advise...
