TV / Professional Nav

[nicke]

Hi,

Apologies for what possibly appear to be simplistic questions - I'm new to this!

I recently took delivery of an X5 3sd M Sport - it has the professional SAT Nav & TV Option. It plays DVD's to the front screen from the loader in the glove compartment.

Am I right in thinking that Navcoder would allow me to enable TV and DVD in motion?

If so, are there any step by step instructions on how I actually 'update' the car once settings have been changed in Navcoder?

I also have the rear DVD option - would this be impacted in any way?

If I take the car in for a service will changing options be picked up by BMW or cause and issues?

Thanks
Nick
