Recalibrating touchscreen in Granturismo

[MartinW]

I have a 2015 Sport with a Carplay setup already installed when I bought it. I've been having a few intermittent disconnections either of video output to the screen (where audio would continue) or, more recently, of the wired connection to my iPhone. Those have typically been resolved, until now, by a whack with my hand on the area where the unit appeared to be installed in passenger footwell, or by unplugging and re-plugging the iPhone.
I decided to investigate further and managed to get a screen up (without the iPhone connected) that showed around 6 icons along the bottom line (sorry, no photo) amongst which was one to calibrate the screen. That presented me with a dot in each corner in turn, to be touched....duly done. Now, calibration seems to be totally out; in "normal" carplay mode, I have a set of icons on RHS including at the bottom an icon for split screen map and audio. Touching that now takes me somewhere totally different. I can go back to the screen where the recalibration icon appears, but I cannot touch it and make it do anything!
Is a "factory reset" appropriate, or am I going to get myself into deeper and more murky water? I have now found a small panel with 4 buttons - marked menu, sel, up and down, which bring up a separate bunch of items (such as image config; vertical, horizontal etc.) and some reset options. I just wondered if anyone can shed any light please.
Afraid I don't know what unit it is - but it does have a couple of boxes hidden away, along with a USB dongle that plugs into one of them, from which the iPhone lead then emanates. Software version seems to be dated 2018, so I guess this was quite an early unit too.

I would message Conaero. It may be one of his installs.

Sounds like a V1 carplay install.
@conaero might be able to help.

Just to close off this thread......had some useful input from Matt (greatly appreciated....!) and after several attempt to get into somewhere where I could actually recalibrate the touchscreen I have today been successful. So now it's all functioning as it should, and I'm much better informed about various menus / sub-menus as well as knowing pretty intimately where all the hardware is located. Also, as useful by-product I seem to have resolved the intermittent connectivity too which was probably what caused me to fiddle with it in the first place. That was down to dodgy contacts on the USB to lightning lead, and possibly on the dongle USB plug too. All duly cleaned and everything put back together.
