I recently got the Blackvue front/back camera installed in my car. I had a few n00b questions, 1. Every now and then it says, "Parking mode disabled, an impact was detected". The car was in my garage all the time, and not even insects were there. Why does it say that? I realize I can change sensitivity, but how reliable is that message, or do I still have to be OCD about checking the car everytime I sit in it? 2. Do you keep the LEDs blinking? (I'm based in the US) 3. The GPS won't work. Any tips? 4. How many hours do you on a 128G card, and what are those N,E,P,M toggle bars on the top of the app? Thanks!
