    Whining noise only when head unit display is dimmed

    I do still have the warranty. The headunit is a DNR1007XR, so it’s pretty new. I’m sending it in for service, but I’m just hoping they don’t send it right back and say everything’s fine. The technician on the phone seemed to think the issue was an RCA cable, even after I explained how I...

    An update. I bench tested the kenwood unit with another amplifier, a different set of speakers, and another set of RCA’s.

    Whining noise only when head unit display is dimmed

    I have the same issue, although I have a different head unit. I notice that in addition to the parking lights issue that is common to both our setups, that if instead I set the head unit to dim through the navigation app (at sunset), that the same thing occurs. Did you ever figure this out?
