HD 12 inch screen replacement and settings change

[murtadaalshawi]

Hello dear Picasso mk2 enthusiasts
I bought a C4GP 2017 1.2 petrol in Denmark EU back in october 2024 (I know not the best choice ), and I have done the following upgrades:

- Monochrome BW to 12 inch HD screen (from UK 2019 model).
- Replaced RCC radio with NAC with help from my friend Elo .
- Upgraded backlights from normal to 3D LED lights.

All the above works fine but I have the following problem which I need your help with.

• My big HD screen does not show the navigation as a big part of the screen. It only shows it as on part of the 3 splits.
  I can choose the other 2 splits in the small 7 inch.

• I cannot change the speed counter and settings to show from left to right EU and not the UK that I have now showing the speed on the right.

• The reverse camera shows only in the small 7 inch and not on the big 12 inch as other cars do.

I tried using the vlud software on the Arduino but didnt find any options other than enabling the big screen and disabling it.

Another additional wish is to be able to change the theme on the big 12 inch to the old themes from the SMEG radio/ nav as I dont like the new boring themes.

So in a nutshell:
- How do I change the main cluster to become a left hand side oriented car?
- Can I use a Diagbox psa software? If so, which?
- Should I reflash the cluster with a programmer using an appropriate .bin file from a EU donor car?

I hope you can help

I've nothing really to add except what did you expect? Parts are different for a reason, so don't expect everything to just work if mixing these, that's why there are different hardware versions for different models and countries.
