Replace touch screen on head unit?

I searched this forum and haven't found an answer. Does anyone know if the touch screen on the head unit on my '21 4runner is replaceable? Mine is pretty buffed/scratched from touching it with dirty fingers I guess.. I see a ton of them advertised on the web ("Replace Touch Screen Glass Digitizer") but have no idea if they're just selling an add-on plastic/glass screen to add to your existing unit or if it's actually a replacement screen. No instructions so I'm thinking it's just an addon like for my phone screen. Anybody know if the screen glass is replaceable?

It looks like the glass is replaceable.

 

A word of caution if you haven't worked with those fine ribbon connectors before: be gentle an take your time. The thin wires and their connectors are tougher than they might seem, but they offer a great opportunity to create gremlins.

 

After perusing this and other videos I guess there's 2 parts to this and I'd only need to replace the digitizer, the part on top that gets touched (this guy got it from aliexpress for $16.80 including shipping, a few years ago)... I'll look into this. Yes, extra careful is the word of the day. Some buff marks on the digitizer is a lot less worrisome than a non functioning screen. Thanks for the link.

 

You must be an engineer or an Electrical Engineer! I'm in IT so I learned a looooong time ago to be very very VERY careful with ribbons on motherboards.

 

Busted!

 

I too was in IT the last 20 years of my working with schools.
