Many thank to all, finally got them working. Even though the manual says that you will need to tell the GPSr you are at a new location if you travel 600+ miles between uses, this is what i did. Satellite page - menu-new position. Both units had traveted no more than 15 mile since last used and I have never needed to do this before, even after I had traveled around 600 miles. Could be some happed since the updates.
Off out a caching.
