I love this new dvd player. Just a few problems. Bluetooth is wonderful. The manual online shows a software interface that is much more updated than mine. Exact same model number. Firstly can I update this software/firmware. Secondly, I cannot find a option to change front and rear bass/treble separately! Big reason I purchased it. I am upset about much of this. I see a model the same as mine that has the things I want lol! Well, also gps capable? Is this true? A external unit? Damn them! Lastly, can I trick it into allowing me to play movies while driving. Not for me but, my son. Help god
