may S-No higher then S-No: 7V8022000 will be OK

Pressing hard shouldn't make any difference. The touchscreen is not pressure-sensitive, but capacitive instead.
However, it can make a difference whether you wear gloves or not, and if you do wear gloves, the pressure could reduce the distance between your fingers and the touchscreen
It's been a long time for me, and I hadn't noticed it with the third replacement XT2.

As far as I remember, the XT2 no longer responded to touch. It didn't matter whether I pressed hard or lightly. At first, you have to press and hold for a long time, and then maybe something happens. After that, nothing happened anymore. It's not even possible to turn it off, because you need the touch screen to do that.
Resetting (holding down the physical power button until it restarts) didn't have any positive effect for me either.

But there's one thing I didn't try a long time ago when I had the problems.
Resetting (holding down the physical power button until it restarts) but with a 12 V power supply and the XT2 in the holder and the ignition on!
This should recalibrate the touchscreen and help.

But if you start having problems, try to get a replacement device. Here in Germany, they are very accommodating, at least with older serial numbers.

I don't think it had anything to do with the speed in my case.

Touch did not respond when:
- low to medium rpm
- throttle idle rpm
- ignition off or on and no rpm
- device only in my hand (to test or try it out)

Mine S-no is 7V80018XX,

I hadn't noticed this problem with the BMW, but with this bike (Gas Gas ES700, same as KTM 690), I'm noticing it. In my case, it only lasts for a second, and pressing the same spot again displays a WP, for example. I don't need to restart or anything. It could be something else, or maybe my screen has been used a lot (around 200,000 km).

I understand that in your case you had to restart because the screen was 100% unresponsive and you needed to restart the device, is that correct?

In my case, it's just that the screen "doesn't respond as well as the BMW's" when I'm driving and experiencing engine vibrations. In many cases I have to press the buttons twice to get them to respond. In this case, it's mounted on the handlebar, while in the BMW, it's mounted on the 12mm navigation bar (perhaps with less vibration).

Thank you very much for your reply.

Yes, that's right, it didn't respond 100% across the entire screen.
But it also started with “heavy” or “sluggish” usability.

It's difficult to generalize the behavior.
But those affected discussed were not only but often with bigger single-cylinder engines.

You still have a very early version, so Garmin should be aware that there were problems with the touchscreen.
Try exchanging it; sometimes Garmin helps.


PS
Pyrenees and ES700 = Great Solution
I spent two weeks there last year – 70% off-road (TET/ACT) – a real dream, It was exciting.

Thanks for your response @proofresistant ,

I called Garmin Iberia customer service today, and they arranged a unit exchange. We'll see what hardware version arrives. I understand it has to be V9 to avoid screen issues.

We'll see what they send

I received the new unit today. The service and speed of Garmin Iberia's technical support were excellent. I received a new unit, code 7V80539XX. Hardware version V9. Just touching the screen in the office, I can tell it responds better to my fingers.

Thank you so much @proofresistant for the tips

(Possibly) some bumpy roads in Newfoundland caused this issue wherein the touch screen became unresponsive. I did all the usual, reset, hard reset, factory reset, it would work, not work, work again, etc.. The worst is when it would get stuck on a screen "DO YOU WANT TO RECALCULATE" and you can't clear it.

I contacted Garmin, gave them the details, without hesitation or anything serious just the unit number, the agent initiated a replacement. Currently my unit is on it's way to British Columbia for a swap. I'll update post as things progress.

That suggests that they know of a possible issue with hardware of a particular batch of Zumos. I don't suppose you took a copy of your Device Information Screen did you ?

Congratulations
It's nice to read that it makes sense to take the time to exchange ideas with others here in the forum.
These words are also intended as a thank you to the other professionals who invest their time here and to inspire others to ask lots of questions.

It is almost certain that Garmin is aware of the problem and has developed a solution, meaning that a fix has been installed since a certain earlier hardware revision.
I spoke to a technician over a year ago and he told me that my second device with the S-N “xy” did not yet have the fix at that time.
However, he did not tell me from which revision or serial number the problem had been fixed.
From what I have observed with myself and other affected users, the problem has not been reported with newer batches, or only in 1-2 very rare cases.
