How do you do the following suggestion?
2) Use a Xenarc brand monitor wired directly to the car's electrical system (ACC line). The Xenarc has a built-in regulator.
By wiring it to the ACC line, the monitor will turn on/off with the car's ignition.

My orignal question was how am i going to power the monitor, and now that I have figured that out, how do I do this. Any feedback would be helpful.
You find a power line that only receives power when the key is in the ON position. There are some devices that are only on when you turn on the vehicle like cigarette lighters, power seats, power mirrors, and the like.
The only way to make 100% certain is us a digital multimeter and measure the voltage of a power line with the key off (should read 0v) and witht he key on (should read ~12v).

The power draw of an LCD is not very heavy.
As such, there should be no issue tapping into an existing circuit for the purpose of powering an LCD. Lots of members power their LCDs this way.
