Well, I have never had Sentry mode record unless I turn on dashcam recording. The center display shows Sentry mode as active, and I will have a message on the IC that there have been x number of events, but no actual recording unless I turn on the dashcam before exiting the car. When I remember to turn on the dashcam, I do have the 10 1-minute videos saved to a separate folder as it should be.
And yes, I have AP hardware 2.5 as I am getting full color from all 3 cameras. Any ideas then? Do I need to schedule a Service Center visit, or am I misunderstanding how it should work?
