A subset of MANCAN Tool features are not working for me

I have a MANCAN Tool A9110 installed in my Alfa Romeo 159 2.0 JTDM.
My MANCAN Tool Smart Control is on VSCMC20230503.

Here are the features that are working as expected:

• Welcome headlights
• Welcome fog lights
• Reverse mirror tilting
• Remote mirror folding
• Remote lock/unlock via smartphone
• Opening cerimony

And here are the features which don't work at all:

• Start engine
• Digital speedometer
• Digital engine temperature
• Digital RPM

None of the latter are as important for me as the ones which are working. However, I'm wondering why they don't work. 

Could it be related to the fact I have a aftermarket Android head unit and the installer having kept the Blue&Me control unit partially connected? I was told it is necessary to keep the B&M module connected even after installing an aftermarket head unit, is this correct?

P.S. Why the hell doesn't this board allow adding pictures or URLs?
