I have a K3 on my BMW K1600GT connect via a PDM60. On noticed the wifi wasn't working and not recording. I contacted INOVV support and we're very helpful! They gave me two trouble shooting steps and the second worked for me. Posting to say thank you to customer support and to help anyone that may have the same issue.
Could you please disconnect the power converter, and charge the K3 with a power bank or usb wall charger, see if the K3 is recording or not? And see if the Wifi light & Gps light illuminate or not?
Could you please disconnect all the wires and connect them again?And please also disconnect two cameras, and connect the REAR camera in the Front port, leave the Rear port empty.Let's see if problem is fixed or not?
