C1, 2015, Bluetooth drops + Screen Share won't load

[Assemblage]

I have a 2015 C1 which I cherish.
Bluetooth connection is always problematic. One day it connects, the other it doesnt.
Whe it doesnt, I have to remove the phone (galaxy s22 ultra) from the list of devices in the C1, and repair them.

2nd issue, is I cant ebter any navigation or screen sharing app, although the user guide says it should work. Tried official USB data cables, but once i click the screen it says 'connecting' forever until it gives up.

Any ideas?

Hi and Welcome.

Unfortunately there's not much 'Citroen' about the C1 as in common with the Peugeot 107 they are essentially a Toyota Aygo. This being the case they use different telematics units than are fitted to other models and I don't have much info about these as they are the exception, rather than the norm.

One thing I do know is that Samsung has stopped supporting Mirror Link, so this may be an issue for these phones once they are updated.
