Man touchscreen not working any ideas?

Basically give me dash /radio screen a wipe with a dash wetwipe .
And now my man radio system screen touchscreen part won’t work. System works via buttons on wheel etc but by touch it won’t.
Any ideas if it’s easy to fix or have i knackered it

Try re-booting it by removing the relay and the fuse for the radio , remove the ignition key , have a brew/break of about 30 minutes , that may get it working again .When removing the key , walk away from the truck ,not sure why , this what a mechanic told me , the NewGen Scania`s have the same problem .

Had precisely the same thing happen to me a few months back. I just left it alone, turned the heating up and after about 6 hours it started working normally.

It’s started working again now. Left it off yesterday as did my head in stuck.on radio 2 all day.
Got in this morning and works fine

Whoever designed the radio in the MAN wants flogging.
