Last year, when outfitting our (new to us) boat, I had to remove some very vintage electronics and entertainment gear. Although we don't have too many movies onboard, we wanted the option of renting movies and enjoying them at home. I also wanted to limit/eliminate as much gear adrift as possible.
I found this unit:
Audiovox : Blu-ray : AVDBR1
It's an indash Blu-Ray player that is also capable of streaming online services. Installation is as easy as putting in a car stereo.
After a year of use, the unit has been flawless and met every expectation.
Another thing to put on your wish list.....
