Infotainment touch screen stopped working after battery swap

[Timk]

So I have a 2015 GT that I did the small to large screen swap last year and everything worked great. Drove it all summer no issues. Go to get the car out of storage this year and the battery was near dead even with trickle charger so bad battery. No big deal go get a new battery and now the touch screen wont work. Steering wheel controls all work, radio stations are even saved just cant access anything without the touch screen working. I disconnected the battery overnight because I figured maybe it was stuck in some odd mode after low power but that did nothing for me. Did the BMS reset with the headlights and breaks, that does nothing. Does anyone have any suggestions? Do I need to reflash or recalibrate something in forscan?

Hello; If you kept the original small screen, have you tried putting that back in?

I didnt see the need, it was not a touch screen from the get go and the new display is working fine. I can see everything, just can't navigate as all the functions are touch function on the larger display.

Try a master reset in the setting menu. That's about all you have.. Also, could check the sync version and maybe update if able.
