Recent installation but having an issue where I leave the vehicle from anywhere from 5 minutes onwards and the time and date reset back to around 03:00. I have tried both manual time setting and auto but it still happens.
Anything else I can check settings-wise
I also noticed that despite the car battery being new and testing with Topdon battery tester showing 12.6v, the DUDU7 display reads 11.6v. Would any in-built memory for time have an issue with this low voltage?
