I put a bunch of pieces together for a sleek phone mount in my 2016 Fit:

This mount comes with a custom plastic piece that snaps onto the space between the 3rd Gen Fit’s air vents. (You won’t be blocking any airflow!) There’s a ball joint so you can swap it out with another phone mount if your choice:

Here’s the mount I chose to swap it with and the ball-joint - MagSafe Mount for iPhone 12 series: https://mag-save.com/products/drive-pro-black-edition-magsafe-compatible

Angled USB-C Cable (I didn’t want a dangling cable):

USB Car Charger RAVPower 36W (needed for maximum MagSafe charging):

Black NFC Tag (mounted on the top - I programmed a Siri Shortcut to automatically launch Waze when the phone is mounted):

…and shameless plug, that’s an original song of mine playing, available on the top streaming music platforms.
