Dietz makes an adapter for e60 I think but I think only a Dealer can recode the MOST bus car. Maybe an Independent who uses Autologic could do it also. MOST bus is the problem.

I know the dietz adapter, it works fine.
But it is possibel the program the most bus - some shops in germany could program the tv free function.

I have called a shop for buy the hardware, but he want to have 2500€ for the hardware...
