The SC 400D is great; I had it professionally installed (you don't have to) and the video and options are perfect. To upload the videos (other than removing the SD card) is through a third party app, DriveSmart. This app is worse than a high school project. It's difficult to use, the firmware doesn't connect to update, it requires a wifi connection for some bizzare reason, even though the dashcam and cell are connected by BT, and the app uses its native map program rather than something like Google Maps or Waze. It's worth getting the dashcam, but pass on downloading the app.
