Some of the new android TV boxes I have seen on ebay do have bluetooth built in and will connect to a SATA hard drive in a compartment inside the box. Check out this video it shows the box http://www.youtube.com/watch?v=3dn6e...eature=related
here is a video on youtube on how to use a bluetooth GPS receiver with android 2.3.1. http://www.youtube.com/watch?v=J2RU4cqXx2E I have also seen 7 in screens with HDMI inputs on ebay. They don't have touch screens but you could use a track ball in the USB port on the box to operate the screen. The earphone jack out to an amp and your good to go. The screens and TV boxes all run on 12v. And a high definition screen not a crappy low res monitor. With all the android apps out there this could be way cool.
