    Kenwood dnx890hd navigation white-ish screen problem

    Anyone ever repaired a Kenwood navigation double din unit. Have newest software and 2020 map update. Have done a hard reset numerous times. Every once in a while the navigation will work. But more times than not , i just get a white screen and says maps unavailable very dim. Kenwood wants $175 just to look at it....

    Here at City of Industry service center, is way cheaper to diagnose it, ~$40.
    In the settings, the 2020 map is selected?

      Yes 2020 map is selected. I talked to Kenwood yesterday and they are thinking navigation reflash. $175+ shipping. Crazy expensive to hook a cable up and run a program in my opinion.

        In these units there is a small board called daughter board. On it there is a micro sd card with the nav software. Maybe the software on that card, is corrupted.
        I would take it out, and try to copy/paste the content on a pc, and see if it will show any errors. There are some files/folders on it, that are not visible to Windows, because they are in a different file format.
