Not sure what year your car is but on the early ones if you have the HDD system it plays a DVD. You don’t need the TV. The HDD has the my music button with the + box when you touch it. You can load 10 cd to memory and play 1 DVD whilst stationary. ( Meridian 380w).
I quite enjoy a bit of the Pink Panther whilst waiting in a car park.
Yep agree with most here. Pure Tech with the 380w Merridan plays pictures and sound of DVD while stationary, the same from USB.
CD’s for music and I leave my old iPod plugged in for about 10,000 tracks to choose from.
Loads of options, even from an old motor!
