Hi Has anyone installed a dashcam into their MK7.5 where it is integrated with the fuse panel - Ie it runs 24/7 but self cuts if battery drops too low?

Dealer is offering to install BlackVue front/rear integrated with the ECU (as they put it but I know it is just drawing power from somewhere like the fuse panel ) THey quoted $1700 which again I know is crazily over the odds.

I know that I can buy a unit for $400-$550 but wonder if it is even worth the effort?

Any thoughts on make/model / installer?
