Hi DCT!
I want to share a CPL solution for the CDV300 and similar (B40) models. It uses a 24mm CPL filter readily available on Amazon, and a neodymium ring magnet:
The CPL filter has an internal diameter of 19mm, so the first thing to do is to find a ring magnet with the following dimensions OD 19mm, ID 14mm and thickness of 1mm.
Its important that the magnet is no higher than 2mm to prevent it from showing in the dashcam footage. If you wish, you can paint the magnet black as it comes in silver.
I used 3M double sided tape to attach the magnet to the dashcam. The lens fits snugly around the magnet, which also allows you to rotate it freely.
High res pictures are attached, on imgur.
