You haven't tried to have you ?. It shouldn't need to be. You can't jump trains as they call them 2* to 3* etc. If somebody has done that then it's likely to behave strangely or not at all.
The experts are on this thread.
MST2_EU_SE_SR_P0253T is the newest firmware for your unit you will find it in: mibsolution.one > mqb_solution > mst2 - technisat preh > firmware > seat_zr The next SW for me is not 0346. or is it only in
seat Ibiza ? Thanks in advance

You would not attempt to reprogram if if it was a
problem.
As far as the maps are concerned the SD cards can go in the end so if it did strange things whilst running the digital map would suggest a new map card.
How to replace is on the
resource.
This

You'd pull the map card out and if it behaved then it would be a corrupted map card. A reboot for a corrupted program is achieved by the long 10 second or so long press on the on/off till the logo comes back up. Sometimes, not often these units go out of memory so you do a reboot. On our standard unit I've only seen it once where the image moved an inche or so on the screen. Reboot corrected it.
Logos can be accidentally deleted via the menu, as said and you have to put them back manually. I wouldn't think it is loose sockets behind the unit in the glove box but could be. Retaining clip. You can get the keys. Run it forward and check the clips are locked down.
Failing all that possibly just a fault in the unit.
Ps also stuff can get pushed into the unit via the CD slot so wandering children's hands can push coins in etc. They would hit the circuit board. I took ours apart once after I'd pushed the map card into the CD slot by accident. Tricky in an Arona to see what's happening under there. My excuse. Dealers refuse to touch them apparently when I read up on the subject of foreign items pushed into the CD slot. I got the offending item out. Pull off the power and disassemble with the unit pulled forward.
