The info BOTH the Halfords stores told you is wrong.
You will 100% definately need an SOT lead. This is needed regardless of steering wheel controls - the Parrott will not work without it full stop.
The steering wheel controls will work as usual and don't require any additonal lead. You will also need the radio code as you are disconnecting the power supply of the radio.
