Swipe to the list ALL and locate Bluetooth

Press it and press Clear Data

Once done, restart the phone and tell me if it connects correctly please

Customer: replied 1 year ago.
I have settings > Apps and within that there is 'bluetooth extensions' and bluetooth MIDI service'am i in the right place? I cannot see an option for 'clear date'.
Expert:  Richard replied 1 year ago.

It is Clear Data, not Clear Date, clear Data on all items listed as bluetooth please.

Its not a standard phone so the firmware is a little different then most

Customer: replied 1 year ago.
sorry, i made a typo. i meant to say there is no 'clear data' option. i can 'force stop'
Expert:  Richard replied 1 year ago.

Do you see Storage?

Customer: replied 1 year ago.
I have found storage and there is a 'clear data' and 'clear cache' button.
Expert:  Richard replied 1 year ago.

Use Clear Data please

Unfortuatelty that did not work, same problem.My phone does successfully work on another vehicle
My colleague has the exact same phone, except he is running Cyanogen V12.1 and his phone did succesfully work with my carIs there anything else you can suggest?
Expert:  Richard replied 1 year ago.

yes, we need to reset the phone.

This will remove all data and return the phone to new, so backup any data you wish to keep first.

Then go to Settings, Backup and Reset and reset the phone.

Once done, set up the phone again like when you first received it and tell me if you can now connect please.

Customer: replied 1 year ago.
I did a factory reset on my phone a couple of days ago. I have had this issue since the weekenddo you really think it needs to be done again?
Expert:  Richard replied 1 year ago.

So you have reset both the car system and the phone?

Customer: replied 1 year ago.
did a factory reset on the car first, then reluctantly did the phone a couple of days later
Expert:  Richard replied 1 year ago.

Can you remove the power to the car system, disconnect the battery if needed, then wait 30 minutes, connect power and then try to connect please

Customer: replied 1 year ago.
ok, will try that later and come back to you. Thanks for your help thus far
Expert:  Richard replied 1 year ago.

Thank you

Customer: replied 1 year ago.
just tried something else. My colleague updated his phone to the same version of Cyanogen that I am using, V13.0His phone now has the same problem as I am experiencing.It appears to be a Cyanogen V13.0 issue with Mazda as the phone does work properly on other vehicles, i.e. my colleagues Nissanno idea what to do now
Expert:  Richard replied 1 year ago.

ok, then install 12 on it if you upgraded from this

Customer: replied 1 year ago.
not sure it's straightforward to roll back a version
Expert:  Richard replied 1 year ago.

You would need to download another cm12.1 based Rom

Customer: replied 1 year ago.
i think this is beyond me.....i guess i'll have to wait for next update and hope that resolves the issue
Expert:  Richard replied 1 year ago.

ok, I also checked for a stock rom but I could not find one for this phone as its not too common, rather then risk it I would advise to wait for the next update.
