RAM mount with adhesive base. Trimmed to fit the taper of the panel. Used this same setup in my 4th gen. Works well and that pad is stuck solid. I like my phone mounted here for easy use and no cables hanging while charging. I don't like drilling holes in my vehicles and avoid it when possible. Phone was definitely not worth a permanent hole.
Note: I angled it in such a way that it does not block my HVAC controls and I can still use that cup holder but usually don't.
