Flashing odometer, no bluetooth

[Mark Carlton]

Hi all,
I have a 2013 1.4 Giulietta that is displaying a flashing odometer. The car operates well in every other respect. My mechanic has tried resetting the computer and doing a proxy realignment but says there's an electronic module that has failed and there is no good way of resolving this issue.
I am wondering 1, if this is a sign of worse to come and 2 if not is there a cost effective  solution to at least having the hands free Bluetooth function working again. Along with this i believe some steering wheel buttons have also lost functionality. Thanks in advance, I'm hoping someone out there has experienced this issue and solved it easily...🙏🤞😬

I have managed to remove the offending blue and me control unit from behind the dash but now need to know if there is a repair service in Australia or where I might find a replacement unit. Any suggestions appreciated....
