    Sony XAV-601BT with a Sony/TomTom XA-NV200TL (The best ever SatNav)
    Hi all,
    I am new here and I have found nothing about my problem so far.
    I hope you can help me.

    Currently I am using 2 rather rare combinations of a Sony XAV-601BT radio with a Sony/TomTom XA-NV200TL navigation module in both of my cars.
    And I am really reluctant to replace them with any newer models as none of them offer the features of mine.

    Since last week I am probably facing the problem with the WNRO.
    The navigation module is constantly crashing and rebooting and when it works it shows constantly the time as 00:00.
    The arrival time is always 00:00 + expected travel time.
    Once I changed the time manually (possible if no GPS reception).
    It is very tiring because I need to click for each day from 1 July 2009.
    In that case the clock is running again, but the arrival time disappears.

    And strangely, the next time I start my car, the manual time setting is lost.

    Does anybody know if my problems have anything to do with the WNRO?
    I can still use the navigation.
    And if yes, did TomTom provide an update already that I have not found yet?

    It does indeed sound like the WNRO problem. Have you tried support?:
