Very nice phope!
Do you mind me asking where you got the mirror covers from please?
The Blackvue install looks very clean, and like you say, hardly noticeable. I have a Nextbase camera waiting to go on mine - makes me wonder if I made the right choice.
I was looking around eBay UK and Germany, as you do, and actually found a set of new, unused and already painted covers on
www.eBay.de for a silly cheap price, and postage was not that much to the UK
There's a few guides and posts on here about adding a fuse tap, which I used to connect a female 12v socket behind the glovebox, added a ground point as you can see with the yellow connector, then threaded the cable from behind the glovebox under the door seal, a-pillar cover and roof lining :
I just used a ignition switched 12v connection, so the camera powers on and off with the ignition - wasn't bothered about the parking camera feature
