I recently purchased a 2013 kx-s and can't for the life of me get the factory head unit to connect to any Bluetooth device. When trying to pair Bluetooth an error "Bluetooth connection failed" appears immediately. It is as if the Bluetooth function is completely disabled on the unit even though enabled in settings.
So far as I have done the following to try and troubleshoot
Disabled/enabled Bluetooth in settings
Removed head unit fuse
Removed battery
These steps above removed existing paired devices but I still get the error when trying to pair anything.
Short of ripping it out and installing an aftermarket unit is there anything else I can try?
Thanks
