2013~2016 CX-5 Bluetooth tab disappeared, commander wheel not working

hi all!

Have a bit of an issue which I cannot figure out, hope someone can help shed some light...

In short: the commander wheel on my 2013 CX5 (NB1 headunit with nav and cd) no longer works, bluetooth tab has disappeared and the phone button on the HU does nothing (!). This all started upon reinstalling the OEM headunit after a failed (as I could not, for the life of me, figure out Key 1Key2 wiring) attempt to replace it with an aftermarket one. What's interesting, is that my phone can still see and connect to the CX5 BT module, but the HU can't seem to detect BT nor Commander wheel.. as if these were literally unplugged.

I have tried unplugging and replugging all connectors, disconnecting/reconnecting the battery negative, disconnecting/reconnecting the AUD1 AUD2 and Bose fuses (3 times - with car off, with car on but radio off, with car on and radio on) but no change...

Any ideas?
 
Hi. I disconnected both cables from the battery and problem solved. Try…

Mine is a Mazda6 2014, but the same radio I think…
