My Sony XAV-601BT with XA-NV200TL and the week number rollover

[jens_bender]

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?:
