...I'm not sure how well they fitted it. I've moved it from the driver's side, level with the top of the cowling to the passenger side just below the cowling. I assume they thought that having the left half of the image blocked out by black plastic was going to acceptable, or they just didn't check
(they must have disturbed something else too as the nearside rear window stopped working after the dashcam install)
As you know the Viofo has a 140° viewing angle so moving to the passenger side and having the top of the unit level with the bottom of the cowling gives an uninterrupted view from the lens...
If after this work has been done, along with the illumination pack fitting, there is still an unacceptable 'rattle' then they can look at the fixings again.
I guess that's the trouble with disturbing the dash etc. and that someone else has done the work!
