Update I can get to AV sources through test mode, my flash disk, AV.exe but not from menu screen

I have a bricked f700bt that I brought back to life using this forum THANKS! However after I get to the pioneer boot screen and press menu I get the destination, contact and AV source screen. I then used the touch screen to try and select AV sources and it beeps but I get no response. After a few seconds it goes back to the Pioneer boot screen I can get into the settings menu and into system settings but again with av settings and av sound i get no response just a beep. Navi settings gets me to the navi caution screen but thats it. The flash drive has been reformatted and the nn746uc-sdmlc-0-1
