I also have a Nextbase 522GW, which I fitted myself. Using the stick on QR mount, I got it to fit behind the rearview mirror so that I can’t see anything of it from the driver’s seat. Your mirror mount and housing looks the same as mine. I had to make up a vinyl patch to cover the sticky mount pad on the outside, as it is creamy white. Looked awful.
Oh great, I've yet to stick mine on with the adhesive mount, been using the suction cup one while I tested the camera out. So didn't realise it was cream
.
Any chance of a picture so I can see where you mounted it?. Did it stick to the black dots on the windscreen around the mirror ok?
Sorry to hijack the thread a little
That’s my installation next post back from yours! 😄 I didn’t want to stick it to the dots, as I wasn’t sure whether it would stick well but, if it did, would it pull the dots off when I remove it.
Oh I didn't see there was a second page. First of all that is nicely installed and very well hidden. Secondly, damn!

You have a different mirror layout to my one. Mine doesn't go into a point like yours so it's harder to hide the camera, especially without sticking to the dots.
I stuck my dashcam on the dots on my last car so might just slap it on there so it's perfectly hidden behind my mirror (I hope there's enough space). Even if I did stick it to the dots and remove it, I would put another dashcam on in exactly the same place.
How come your's doesn't have the big magnet thing on the power cable to avoid interference? Didn't you install it?
I've never seen that F770 cam before

. Looks very nice a sleek, no screen tho? I'd miss that.
Also OP, you can get one with a screen that just turns off after 15/30/60 seconds (depends on brand).
