as for a cell phone dash mount, get something that isn't suction-cupped onto your window. if it drops, likely reaction is that you will attempt to grab it. cant have that while you are driving. very dangerous. check out things like this
as for dash cameras, there are a whole slew of them out there. 2 of my preferred companies are COBRA and UNIDEN but you should do your own research into what you are looking for.
I use one of these, which mounts the phone just above the infotainment system screen. It works well for me. https://www.amazon.com/gp/product/B001DQQBVW/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
