These are great cameras. I did not hook up the parking assist but installed one of these dash cams in both of our vehicles and it took all of 2 hours total give or take.
I did experience difficulty setting the time/date stamp but was finally able to set it in both cameras. One camera was way easier to set than the other.
The only con for me is that the user/install manual doesn't convey much information on the features and how to set or use them so it's a lot of trial and error but easy enough to figure out. I recommend these cameras. Great visibility and 1080p the resolution is great as well.
Default settings are perfect. The reverse cam add-on is with back up view is exactly what was needed. Very pleased with this cam and setup.
Have been using this dash cam for about a month now--The battery life has been great (still has plenty of juice even after not driving my car for a couple days and does not reset dash cam settings back to factory). Quality of the recordings are clear during the day. I also often use the dash cam as a backup camera to assist with parking and checking distance between rear bumper and objects such as curbs, bushes, stationary cars, drive ways, etc. It took me a bit used to since this is my first mirror dash cam--I was not used to how much glare you can have while using the mirror dash as a regular rear mirror. After you get used to all the features and adjusting to the right angles, it's a great dash cam overall.
