Hi Nick,

Sorry for not responding to your PM, I have not logged into X5 world in the last few days.

Anyway, did I get the problem resolved? Yes and No!

I have found out what the problem is but I have not had a chance to bring it back to the dealer to get it fixed yet.

The DVD remote control works on a radio signal, not on Infra Red like a standard TV remote etc.

The radio signal from the DVD remote is picked up by the Remote Central locking system (as if it's a standard key), which then transmits the DVD commands to the DVD system over the bus.

Because of this a new remote control has to be "Learned" by the car, just as if you bought a new key for the car.

You can find out more info about this in the folowing document;

Page 10 states that

"The commands entered using the remote control of the rear seat entertainment are transferred via the transmission frequency, which is also used for the radio remote control key function. The frequency used is dependent on the national variant and therefore relevant for coding. The commands are received by the FBD aerial and routed via the antenna amplifier with diversity module to the CAS3. The CAS3 converts the signals into K-CAN messages. The commands then reach the RSE control unit via the K-CAN."

Page 21 goes on to state that

Note: Remote controls are not interchangeable. Only the taught-in remote

control is functional in the vehicle."

My dealer has confirmed that this is all true and that I need to bring my E70 back to get re-programmed, but I have not had time yet.
