I installed a Dudu7 8+128 10.36 inch and I have a 2014 Peugeot 308 and use the Simple Soft RP5-PA-001, which is designed for my car.

But I find the canbus integration very limited.
I cannot use the build in A/C app, only the generic floating button.

Also the vehicle information interface does not work. I can only use the old interface like on any FYT unit.

I can’t only choose this protocol to get it working: XP(Simple)>Peugeot/Citroen>408>XP
So what is the solution? Can’t I use the software as intended? Do I need another Canbus box?
Because right now, the unit doesn’t make that much of a difference from the Junsun 7870 I just upgraded from. I expected a bit more to be fair…
