JVC headunit.

Hey there I just wanted some help with with jvc headunit touch screen Not too sure what the problem is. I have had the Audi since April 2015 with no issues. I have took the unit out check all the connections, the ground, voltage. Every thing looks good. So anyways take this morning I start the car headunit comes on its all good. Lunch comes started the car and like there is not even power going to it yet I can go somewhere shut it off then turn it on and it's back on. I do plan on getting a new headunit down the road.

Gotta be either a loose connection or a bad headunit
