Anyone figure out how to get the BT audio to work? I’m in engineering mode but have no idea what to do to from here. I’ve read on other posts there is a key combination you can put in to enable it but it’s different for each model and of course the few models that post lists the key combos are not the gl450….

What can I do and change with this menu?
