That probably won't work but hey ho...just downloaded Canadian mx30 mazda connect guide and they have a hbc enable/disable function shown in the menu on exterior lighting. I wonder if European vehicles had this option removed or will it come in future sw upgrades? See extract from Canadian connect guide
