Postscript to my post above.

I just took second unit I exchanged for today in Car.

It took about 4-5 minutes to lock onto Satellites and found my loction.
Placed unit on passenger seat and it was very accurate.

Maybe my first unit had an issue because satellite meter did not move past first bar for 10 minutes .

Based on what I just saw I can live with its performance.

Software is not great. Street names were not right for two roads near my home.
