About these radios, people are calling it "delamination" or it's a screen protector. Both of these are untrue. The factory radios don't come with a screen protector similar to a cell phone but you can buy them and put it on, they are very thin and cheap to replace. From my investigating, because my radio is doing the same thing, what is happening is the LOCA (Liquid Optically Clear Adhesive) which is cured with UV light that was used to bond the Digitizer ie touchscreen on top of the LCD screen is getting too hot and is actually seeping out the bottom of the radio screen assembly. When i took my radio out to look at it on both bottom corners of the screen was balls of gooey clear sticky glue. After reading up about these radios, mine is a Panasonic 8.5, they were assembled in Mexico, the screen assemblies are made by LG probably in China. The glue has a set value of temperatures to be stable in and it's evident that a closed vehicle gets very hot and pushes the temp way past the stable point so the glue just kinda melts. It runs out the bottom and the air gaps left behind are most always at the top and sides and where the air gap and glue that is still intact meet on your screen that is where all the button pushing is going on by itself. I am pretty sure it's worse if you live in the south and have a dark colored vehicle. I have thought about repairing mine, there are a few videos on youtube that show someone removing a cracked touchscreen and installing a new one and phone repair videos too which is basically the same thing except smaller scale. Problem is the touchscreen is thin and delicate and removing it without cracking it is tricky. Phone repair people use specially heated pads and screen holder to warm up the screen assy then use a thin wire to slice between the screens and pull them apart. Then you have to remove all the old glue then reassemble with new glue. My thought on this was to reassemble without the glue but use the thin tapes that most early screen assemblies used as it only went around the edge of the screen and left a air gap between the screens. The LOCA glue was used because it cut out the screen glare from early radios and as the screens got bigger the glare was more noticeable to engineers, i guess. My other thought on repair was to seal up all the gaps around the edges except the top and reintroduce some LOCA glue to fill all the air-filled areas and cure it and see what happens to all the button pushing. My gap line is right across all my radio station buttons so channel surfing is out. I preset all my buttons to one station so i can at least listen to the radio. I think i will try the glue adding first as it would be the cheapest fix and most of the time the simplest fixes usually work the best we will see. If it does work I'll make a new post about it for sure.

It should be rather easy to repair that.
I would say, if you are careful. add some acetone on 'wire' (you need to be extra careful, but it does work the best)
Using playing cards work really well, and less chance of breaking it.
Depending the loca glue they used. wd40 could work as well.
Other option, as long as it's still working. Instead of taking it off. carefully apply more glue in damaged area.
some people have use small paint brushes to do it. with roller and UV.
Worth trying vs having to buy whole unit.
In my view, the reason some of you might be having this issue, is the Sun. With UV PhotoInitiators, they keep curing over time.
Angle of the display, and If you drive, or leave your truck in Sun for hours. Over time, it will keep curing.
Just so you know, just cause it might have been done in Mexico doesn't really matter. It's not 'person' thing.
Whole process is done high-end automated Machines, usually done in Class 1000 clean room.
Also possible either glue or machine was had an issue, but would be extremely rare.
