Hi,
Sorry but this isn't something I can really
help with as I never utilised that feature of the dashcam. I think it can auto connect when it's in range of a wifi network, such as when parked on a drive with good wifi signal. It would have to remain powered while it did this though, possibly via parking mode?
Sorry I can't be of much
help! Best of luck getting it sorted.
Regards,
Lozzy.
