Ok... I managed to pick me up 2 topo cards, 1) Polaris SW card and 2) Pro East card. Both cards when inserted (separately of course) say "loading" at bottom of screen then message goes away. So with the SW card, living in TX, I didn't notice any overlay while driving through local city neighborhood, I figured that's normal because the SW card doesn't cover TX. But now when I insert the Pro card, which includes Texas, it's the SAME just like the SW card, no overlay.

Is this because I'm in city? Or do I need to do something to show the topo overlay? How do I make sure the card is functioning properly? Thanks
