i used RAM Mount components and mount from my rear view mirror.
the cupholder to the left of the wheel(assuming usdm drive car) would prob be better in the long run than the vent mount option. id be nervous about being so close to the window myself.
this isnt 'RAM' but i used it with their items to attach: https://www.amazon.com/dp/B0989PNG3C?psc=1&ref=ppx_yo2ov_dt_b_product_details
