Well. My factory screen isn't a touchscreen. It's a infra red controlled screen decided by sectors. And particular buttons on the menu are placed where sectors are. There's no calibration and it's all together probably unbreakable.
But the thing is: I do not want to implement new method of screen control in original Navi soft. I need real touch screen just to control my Car PC
I'm about to buy in nearest future. I really don't think sticking such a thin layer of transparent material (whatever it is) may cause problems with working my stone-age infra red sensors. And that was my only concern in that case.
My other issue is: is it okay to put your after-market touchscreen with 153mm/85mm working area on my screen that has visible dimensions: 158mm / 89mm. So about 2mm border of non-functional touchscreen would be on my factory screen. Can I practice that? I'm not gonna use any stylus on the screen so I don't think I may damage passive are of the touchscreen.
Correct me if I'm wrong at some stage.
Does it all make any sense?
