I was trying to test my 3D maps and I chose downtown L.A. civic center as a starting point. I selected "start from this point" and the pop-up box said "deleting current GPS setting" or something to that effect and I clicked yes. Then it did nothing. So I clicked "return home" and it started to calculate and just stuck there...nada . I re-booted the system (eject+reset button)...same thing. Reset the system to the default navi settings. Same.

What am I doing wrong or what do I need to do?

Thanx,

Bud
