Help! Retrofit Navigation Business CIC (Mask II)

[copyright]

Hello!, I´m a 1addict from Spain. First of all, my apologies for my low level of English..

I know this forum is the most important about our Bmw 1 series and I hope you can help me.

I´ve a Bmw e81 Limited Sport Edition, manufactured in July 2007.

I want to replace the professional radio Cd for a navigation system business mask II CIC 6.5 inch screen (i think that this unit haven´t USB), with 8-button iDrive. This unit was provided by a 1 series manufactured in 01/2008.

The Mask 2 haven´t USB, so I need help for a few questions:

- The mask 2 reads navigation DVD?, How to read music if the navigation disc is inside?

- It would be possible recode my car without change car production date? (note that is a CIC without USB).

Finally, what are the codes for the unit works fine?, The car is equipped with PDC front/rear and HIFI system.

Thanks a lot. Here I leave a pic with your cousin a F20
