Carminat Bluetooth DVD Oo?

Can anyone please tell me something more about this navigator, i cant find the specifications anywhere. Is it able to play Dvds (like videos, and music), does the 6 cd changer mean you can play dvds aswell or only cds ? And the most important thing I am eager to find out, is it easy to use, and ofc is it worth the price.

any help would be great, Thank you
