Hi,
I have a 23 is350 F and have purchased the VIOFO A139 Pro 2 channel dashcam and was curious if the rear camera would fit with the powered sunshade?

 

I had this same question and was unable to find any answers, I have a ‘23 IS500. I just went ahead and ordered a Blackvue 2 channel dashcam and figured I would suck it up and find a workaround if necessary. Don’t know about your VIOFO, but the Blackvue’s rear cam does not clear the sunshade (at top center of course). Being that it’s a small cylinder I’m just planning to install it on top of the third brake light, and hope it has a good enough viewing angle there and won’t be in my view much.
