Hi, Sorry for late reply, I manage to get the camera stuck to number plate ... but for last 1-2 months .... the main screen become unresponsive after random time, has keep hold of home button for long then it comes on But when put in reverse, the screen always shows reverse camera. And as soon as I disconnected the box and reconnect wires the screen came back on instantly and since then no issues.
No idea is the box need replacement or some firmware update.
Has anyone else faced this type of issue.
