For some bluetooth headset it's working only in terminal the configuration (bug not only on Utouch but the bluetooth package )

$bluetoothctl
[bluetooth]# power on
Changing power on succeeded
[bluetooth]# discoverable on
Changing discoverable on succeeded
[bluetooth]# pairable on
Changing pairable on succeeded
[bluetooth]# agent NoInputNoOutput
Agent registered
[bluetooth]# default-agent
Default agent request successful

scan on
pair C9:50:76:A2:XX:XX
connect C9:50:76:A2:XX:XX
trust C9:50:76:A2:XX:XX

If succesful it should connect automatically

It looks fine. But when I put pair XX:....... the car says it's not compatible. I have a previous connection that I would like to delete but I don't know how. Thanks

you should do something like

remove xx:XX:XX:XX:

On the terminal with localhost and su I make the commands:
bluetoothctl
power on (if it is off it gives an error. But putting on grafically it puts no error)
discoverable on
pairable on
agent NoInputNoOutput
default-agent
scan on
trust C9:.... (I prefer putting this the first one)
pair C9:... IT GIVES AN ERROR:
Failed to pair: org.bluez.Error.AuthenticationFailed
I don’t know why. In other tryes the car says it doesn’t pair to this type of phone.
PD: Whith the command: remove C9:.... I was able to delete the previous pair.
Thanks,
Cesar

Maybe it's the type of agent/profile you have to change to satisfy the c4
I would suggest this order
Pair
Connect
Trust

Cesar,

Now that you're able to get an error msg I strongly suggest to look on google : https://encrypted.google.com/search?hl=en&q=Failed to pair%3A org.bluez.Error.AuthenticationFailed

You're problem might be linked to a driver bug, but i doubt is linked to ubuntu touch itself, even ubuntu.
Good luck
