When you switched the constant power and ignition signal wires, did it shut off while driving? I see you said it was wired correctly but It sound like a poor connection on one of those wires. Will the head unit turn back on again after shutting off while you’re driving?

Check back at the wire harness adapter and look at the connector pins. Make sure they’re all seated correctly and do the same at the head unit. If the factory radio never had this problem then it’s most likely what was recently added, harness adapter or connector pins/ crimped connection from pin to wire.

If you are trying to watch a dvd while driving (which you shouldn't) and without setting your parking brake then you'll need to ground the parking brake wire in the harness for your head unit.

yes, if your Jvc has a Bluetooth capabilities. You can ask a vendor that sells phone to car stereo receiver. By the way, I will not trust a phone to car stereo cable connector. Most of them doesn't work

Go back and double check ALL of your wiring..If it's getting hot that means one or more wires ARE NOT hooked up correctly..

You can get parts here. Look at the ribbon cables running from the T-Con board down to the connectors on the screen. The board itself is probably causing it but check the cables first. You can get parts online from here: TV Parts Universal TV Stands DLP Chips ShopJimmy

Check and make sure the ground cable is clean and tight on the battery.

Taking a flying guess the wire could have two possible functions - either providing the radio with additional illumination when the vehicle lights are on or if the illumination is permanent it could dim the display, etc. when the lights are switched on.

You probably have a bad switch on the face. If you have a switch that is letting any voltage through, the microprocessor assumes that it is receiving a command. The microprocessor can handle only one command at a time and locks up.
