2004 Acura TL deck/nav

Over the last few days I have been adding aux sources to a 2004 Acura TL Factory Nav and stereo with adaptor from PAC. Everything was fine except some sort of feed back from the headrest screen a/v switcher to the front. Everything was working except for said problem turned car off and walked away, came back turned on the car and the factory Nav controls touch screen and buttoms stopped working as well as the factory radio does not seem to have power all fuses in the 2 main panels ok. Any suggestions, similar experences or ideas would be of great help

first off heres the audio wireing for the car next remove all powers and  grounds you have added, find blown fuses and replace. check all your wires for shorts to each other and to ground. make sure the wires you are tapping in to can suply the new equptment with enough power. video is very senstive to voltage and ground. short common grounds and stable power are a must. next i nee to know what pac part #'s you used

It is the universal video intagration mod from PAC and the HON-Aii audio input. When I got back to the car on friday and started it everything was back to normal. We decided the car is a hauted rebuild as other mystories occured as well.
