Now I'm not sure if this belongs in the Car thread...if it does mods can delete it. But anyways, I have a touch screen in my car...the only problem is that it isn't wired to anything...I have a bunch of out puts from it..but it isn't powered. I'm not sure what brand it is..it just says TFT 7" wide screen across the top. I want to wire it to a GPS of some sort but I'm not sure how to power it. It has a USB cable attached to it among other things. I will take pictures. If anyone has anything similar in their car...wanna help me out on how to power this thing?

The car thread would prob be your best bet.

Although, if you are gonna fool around with electronics, perhaps a mechanic would b a better bet.

Take it to a Best Buy or similar car stereo shop and see if they can help you out.

fistly the screen is powered by the cars battery, generally sat navs are powered by the car battery via a 12v cigerette light socket inside the car
