Morning, thanks for the quick response. I already have the hard wire kit to install and intended to run it underneath that pillar moulding. I have seen both the Youtube videos but will watch the i20 one again to refresh my memory. Thanks again for the information.I can't comment on the air-bag enquiry, but the following YouTube video suggests how a dash-cam might be wired up on a current model Hyundai i10.
In that instance the dash-cam was powered from the car's 12V accessory socket, but if this approach is disliked, there's a video (relating to an i20) that offers an alternative powering method that piggy-backs on to a 12V fuse-way.
