Interesting.It shows the temperature in the top (see picture) you need to have a working Canbus decoder (on some car does it work without) for it to work same for the car battery voltage and so on.
I have canbus decoder installed and it works fine.
It shows door open/close, battery voltage, steering wheel control works, shows A/C status.
Show temperature enabled but does not show on the top bar.
Not really sure where to look for the problem.
