Hi Slipperyturtle.My blackvue camera mount is really on there and no problems with the sun here in Hawaii. The pads are decently cheap... maybe an option for you to try?
5x BlackVue Mounting Double Side Tape for DR600GW DR550GW DR500GW DR400G DR380 634420987025 | eBay
I have been thinking of purchasing a Blackvue for ages, but have chickened out as I have a 2015 Limited edition with air bags everywhere. Two questions, did you run the connecting wire between the cameras as described in this post? and secondly, is the Blackvue as good as the promotion suggests? Thanks Tom
