Mazda CX-9 hands-free reset
 

Hello,

I just bought a used Mazda CX-9 2010 Grand Touring without Navigation with 4.3" Display, and I am trying to figure out how to reset the hands-free Bluetooth passcode.
When I try to use the “Talk button”, I am prompted by the system with the following message: "Hands-free system is locked, please state passcode".
Since I didn't setup this passcode initially I have no idea what it could be. I have tried guessing what it might be but have had no luck.

I am also trying to delete the links to the old saved Bluetooth devices, but the system is giving me an error as well.

So I guess a simple reset to the Bluetooth system would resolve both issues.
Any help would be greatly appreciated.
Thanks,
Pascal

Have you tried 0000 or 1234 as a passcode?

Yes of course. I tried several combinations like 0000, 1234, 1111, 2222, ... 9999
But no luck :(
