DC-DC power supply is the better way to go for nearly every situation. The popular ones also have a startup/shutdown controller that will turn the PC on with your ignition, saving you from having to manually turn the PC on.I am also a bit confused about power, weather or not I should use an inverter, or a dc-dc power supply.
These are all first-generation units and they all have issues.I have seen the Lilliput and Xenarc in-dash touch screens and have tried to read as many reviews as I can on both. I really don't care if they are motorized or not, I just want the best quality.
All the bells and whistles?In closing, please feel free to post suggestions on hardware, software, or just general how-to's I want this to be a clean and reliable system that has all the bells and whistles. My thanks to all.
I don't see a relay board to control door poppers and actuators for a bed cover.
I don't see a second monitor, which should ideally be a flat-screen hi-def TV that is flush in the underside fo the bed cover and swings out when the bed cover is raised.
I don't see air suspension control.
I don't see any video recording.
There's no HVAC control.
You're missing lots of bells and whistles!
Seriously, though, you've got a pretty good handle on what you need and want. The only thing I'd investigate is how well your radio tuner picks up a signal when it's inside your truck and you're rolling down the freeway at 70mph (or however fast you go). Most of them have horrible reception in a vehicle, since they are designed to be used on a stationary desktop PC.
Welcome to the madness!
