Hi just completed the first upgrade to my new car, Grom BT3 in the boot. Pretty straight forward other than a scrapped knuckle unplugging the CD changer. It all seems to be working ok but I have one question, it says in the manual to press scan twice to voice/dial or use Siri. I can do this via the menu on the pop up screen but is there a dedicated button as that is not really practical while driving. Thanks in advance.
