I've been searching for a phone mount to stick in my 6620 for this fall.  I recently got a new Samsung Galaxy S9.  Right now, I'm leaning towards this: https://www.amazon.com/dp/B0754NDNT8/?coliid=I2DZ3CYI4557D1&colid=3FVZNXRVDS0QR&psc=0&ref_=lv_ov_lig_dp_it  Instead of using the suction holder, I want to find a way to bolt it securely somewhere on the right inside the cab.

I wanted a holder that would allow me to utilize the built in wireless charging capability of my phone, would securely hold the phone over bumps, and would have an easy, quick release so that I can answer the phone quickly and then put it back in the holder all with 1 hand.

I've never used the "X holder" style but it makes me wonder how it holds the phone when going through bumps and if you can insert and remove the phone 1 handed.

The same seller of the product I linked above sells the same holder without the wireless charging capability for about half the price.
