Hi there, is it a pipe dream or might it be possible to view and edit configs/files on a cheap OBD2 display like this one? I'm satisfied with the info that is available on them but interested particularly in the possibility of creating additional custom themes or hijacking existing ones to personalise the display, such as tailoring it to fit the rest of the displays in my car.

I've tried looking for any similar questions online but haven't found one yet so I'm interested if this is something that I could experiment with. I have absolutely no issue taking it apart if it means looking at what's on the PCB to see if it's possible for the chance of helping anyone else who's similarly curious and has one.

I'm wondering if the mini USB port on the back can be a potential way to access or flash files onto it or if it would be something that might require the complexity of modifying or replacing parts of the PCB as I've seen can be the case with the way some of these kinds of products are made.

Thanks for any help to anyone who doesn't mind humouring the idea and for those who may have more of an understanding of the type of accessibility these products have or for anyone who may have one of these and a similar question.

The first image (OEM 5JA920940A) is the one I have found that I would like to replace my current one with (not sure which OEM #) - which is the second image.

EDIT: Please ignore the km/h unit on the second cluster, my car has the mph version.

I'm unsure of the compatibility and was wondering if anyone here either might know if it would be possible or how I might be able to find out if it could be. The reason why I like this one is mainly for the Maxidot display as my Fabia only has the Minidot, but I also like the additional gauges for coolant temp and fuel.

My car is the Skoda Fabia MK2 1.2L

Thanks for any help
