Yeah, I'd guess that a larger display would use a lot more power than
the smaller screen already on the H100 unit. I'd venture that you'd need
an external power supply. Sounds like a neat project though.

As for where to look for larger displays, I'm sure there are plenty of
resources out there to check, based on which style of screen you want
(TFT, etc) and what size you really want. I'm guessing something "4
times bigger" than your H100 series screen will put you in the 8" screen
range ... here's an example of a screen approx 8.4" diagonal viewing:
it'll do 800x600 resolution, 18-bit color, etc.

Here's their list of all 5.0"-8.8" screens and basic capabilities:

Problem with that site, of course is (a) they only seem to list SHARP
products, and (b) they don't list prices. But you get the idea.

As for wiring, I imagine you're on your own for that one. I'm pretty
certain that you'd have to come up with your own circuitry to control
this new panel (microcontroller, etc), and somehow get signals from the
H100 system to tell the microcontroller what to do.

Might be cheaper to buy a $400 laptop, wire its power supply into your
vehicle's electrical system for power, and use the USB controller to
mount the H100 as a local drive and have winamp running on the laptop /shrug

Good luck with the project,
