I use this one, Spigen Kuel A200 Car Phone Mount Magnetic Air Vent Phone Holder QNMP Compatible & Compatible with iPhone X / 8 / 8 plus / 7 / 7 Plus / 6S / 6S Plus / Galaxy Note 8 / S8 / S8 Plus & More - Black https://www.amazon.com/dp/B0109JIQ0W/ref=cm_sw_r_cp_apa_i_FSTdBbGNRQDXV , and just find the sweet spot for the metal plate. Also I put the metal plate on the inside of the case, not on the phone. I just use a regular car charger. My wireless charger still work also
I use this one and its perfect. I don't even want an infotainment screen, just this.
Depending on where you'll be traveling (i.e., depending on the temperature), you could get a magnetic phone mount that clips to your vent. Then turn the AC on - the AC will blow right at the phone!
Doubly good, since it will (hopefully) put your phone in a convenient navigation location.
I have this one and it's been great; there are tons of others on Amazon pretty cheap.
