I tried the Pilot III on a flight yesterday. It acquired satellites quickly despite having been moved some miles since switching off a day earlier and it navigated OK using the HSI presentation towards a waypoint selected from the database and also accepted a newly created waypoint for my home base.
The data screen was correct other than the date. UTC time is correct.
I've found the information below on the Garmin website.
On this basis, I'm going to carry on using it as a handy little backup as is. The displayed date, sunrise and sunset don't matter.
If yours is misbehaving there must be something else afoot and I can't believe it's the 2.06 to 2.07 update.
My unit's memory battery seems to have recovered some capacity after a few days on charge too which is handy.
"What is the Effect of a GPS Week Number Rollover Issue?
For GPS devices that are affected, after the rollover occurs, an incorrect date and time will be displayed. This incorrect time will also be used to timestamp track logs, compute sunrise and sunset, and other functions that rely upon the correct date and time. However, the positioning accuracy will not be affected. The device will continue to deliver the same positioning performance as before the rollover."
