I finally installed my dashcam after waiting for the homelink adapter from MX5Things. Usually everyone recommends Dongar. However, I wanted to use a Thinkware camera, which MX5Things allows.
Once it arrived, I tried installing it on the white connector behind the the radar cover, only to discover that it doesn't work. When I researched for homelink adapters, Dongar sells two different ones based on the mirror. When a few people mentioned that their framed homelink mirrors used the same adapters as the frameless one, I think it's this connector behind the radar cover.
The framed style that both Dongar and MX5Things sell is based on the connector behind the mirror itself.
While the adapter from MX5Things says it's for the MX-5 and CX-5, it clearly prioritizes the former. The cable just works on the CX-5. If you're using a USB-powered camera, the length should be fine. However, since this adapter is meant for a Thinkware camera, it's too short. This caused me to use the radar cover as a mounting point.
At first, I thought it would work, only to discover that thr cover isn't flat. As a result, the camera is tilted. Based on the footage, it's not ideal, but just tolerable. Had I hardwired the camera, I may have not encountered such a problem.
