I took a replacement for the deceased blackvue dr550. Small, without a screen, cannot be seen behind the mirror. Resolution 2k in 4x3 and 16x9. There is voice announcement of all actions, there is ADAS, there is built-in GPS, built-in Wi-Fi and for me the main thing is support for tire pressure sensors and voice announcement when there is some problem with the pressure in the wheel. Small, without a screen, cannot be seen behind the mirror. Supports tire pressure sensors. So far everything is working fine. |
