I live in Az where the last few days it's been above 110°. I also have a dongar pro adapter and have not yet noticed my digital rearview mirror flickering.
Me personally wouldn't want silicone. Lint and dust seem to stick to it. I had a silicone ear buds case protector and I hated it. Slimmest wallet I know of is something like the magpul daka wallet. Less than $20 on Amazon

The wider coverage on these mudflaps has made a noticeable difference—my truck’s paint has been staying free of new rock chips since installing them. I’ll be picking up the silver or black ones next to better match the look of the truck.
If you are talking about the one I posted it slides over the stereo. Not gonna say it's impossible for it to move but it would have to slide up over the stereo. Double sided tape could be used for extra security. I promise this would work for 80% of the people here who never go off the pavement.
I went with this! Saved some cash and got some storage space. Pic was taken before I got the ball mounts.
