I went with a cheap Thinkware F50 to start, mostly because I was heading on a road trip and wanted something I could pick up locally and install quickly. It is decent enough, has parking mode and is discreet. That said, I will likely upgrade to something in the near future that has Wifi capabilities and a rear camera like the Blackvue dr650gw-2ch.
Wiring was easy with the following from Amazon:
Lumision FAST SHIPPING* ADD-A-CIRCUIT ATR MICRO2 FUSE-TAP x 2
Lukas Power Safety Device, Uninterrupted Power Supply (Upc) - Type C
By removing the tray left of the steering wheel I actually found it very easy to remove fuses using a fuse puller from the auto parts store. Accessing it from under the dash would have been a nightmare.
