    Thank you to Frank for the Link , I have not cured the issue yet but I surely have learned a lot about how this functions . Hidden screens and panels etc.

    Nuvi 780 Wrong Date

    For some reason my Garmin Nuvi 780 is showing the wrong date.. I've tried a firmware update (v5.30), a but that didn't work.
    Today is March 19th, and the GPS is showing Monday November 3rd, 2031. I've tried a total reset also..
    Does anyone have a fix for this issue ??

    I would call Garmin and ask them how to fix it. You are off by 19 years (this is a possible clue). This was a fairly common problem with a bunch of earlier model units. They had instructions for getting it corrected.

    Take a look at this link, there may be something helpful there.

    Re: Garmin Nuvi 780 - Wrong Date

    Ok. I called Garmin.
    They are aware of the issue, and the engineering dept. is working on a fix in the next firmware update..
    My current firmware is v5.30. Just in case someone else is looking into this issue...
    There is no time line as to when this fix(update) will be available..

    Re: Garmin Nuvi 780 - Wrong Date

    Bill,

    I have the same issue with me 255W. I called support, but the person I spoke to had never heard of this. They suggested I reset my device, but that did nothing.

    Did you talk to anyone specific? As you know, this is pretty annoying. It screws up daylight savings time, as well as when the device goes into day/night mode.
