You could use one of these if u have a powered mirror.

https://www.amazon.com/dp/B07KZSBC54/ref=cm_sw_r_cp_awdb_t1_s9..DbRAJMMNC Gives you a USB at the rear view mirror.
I just went thru this with my 2018 CX-5 and my gf's 2021 CX-5
For 2018 CX-5 this adapter plugs directly into the connector in the mirror: https://www.amazon.com/gp/product/B07KZSBC54/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1
For 2021 CX-5 this adapter connects to the connector inside the cover: https://www.amazon.com/gp/product/B082ZSFQ8C/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1
Not sure what's in the 2022, the connectors are very different so they are not interchangeable
I bought one of these to avoid having to do any wiring:
You need this Dongar adapter, for the non-signature.

I would be interested on your take of the Garmin mini. I liked the size, but what a pain to connect my iPhone to it. I ended up using my Viofo A129, that I had in my 2019 CX-5 prior to upgrading to a 22 turbo.
Anyone using the Dongar Mirror to Dash Cam Power Adapter?

I went with this plugged into the rearview mirror. Works perfectly, and looks very clean.
