Hello. I just bought 11 X5 05/10 production with OEM Rear Seat Entertainment (Flip single screen). Is it possible to somehow watch movies from USB stick, ipod, android device or connect something to RCA jack to watch movies NOT from DVD's that I have to always carry.

If relevant: my vehicle doesn't have Premium sound, therefore no DVD changer but I have USB in glove box and in the center arm rest.
Thank you
