I just got back from the W. Palm Beach area and my Nav had problems down there. I drove down on I-95 and when the road got close to the turnpike (around Jupiter ?), the Nav got very confused. It kept recalculating every couple of minutes as if it didn't know where it was. I followed it at first and got onto the pike, but then it almost immediately told me to get back off (even when there was no exit!).

Have others experienced Nav problems in the area and is it due to the 2 roads being relatively close together?

 

Yeah!
My Rand-McNally is like 5 years old and with all the new construction and renumbering of exits, I can never figure out exactly where to get off...
