Apparently need to buy a module to remove the safety features that block dvd/certain features of navigation/phone book while car in motion/gear engaged.
Contacted Elebest and Autospritze - module not available.
Net search revealed the following.
Want to enable the feature for passenger to view. Once enable, also keen to install latest digital TV + keen to install 2 monitors for rear seats viewing.
Experts in the forum, assist pls.
