Already tried the second method 'when the Bluetooth "bongs" quickly turn down the volume knob' and this works briefly but doesn't seem to save the setting.
Will try the first method and see if that works and retains the setting.
Thanks for your help.
Think I may have answered my own question. Did a bit of digging on my latest version of Elsawin and came up with this. Haven't had chance to try it yet.

Tones for Bluetooth connection between phone and vehicle are too loud.
Hi, can anyone tell me how to reduce the volume of the bluetooth confirmation tone as it is too loud and all the neighbours can hear it when phone attaches and detaches. All help greatly appreciated. Cheers. Car is 2007 TT Roadster with Symphony and Bose.
