I found lots of success using MetroWizz to simultaneously load MetroGuide North America v5 and Topo US maps into my GPSMap 60C and into my GPSMap 60CSx. My only problem was when I did an address search on my 60CSx it could only search the map segment in which the cursor was pointing. It was as if all the other loaded maps did not exist. In order to successfully search for an address I have to make sure the cursor is within the map segment of the desired address; kind of problematic if I don't exactly know what map segment the address is located.

A Garmin rep told me the problem was that the 60CSx was programed for NT map format (I guess that is why they have a City Nav NT and City Nav non-NT). Anyone know how I can get my 60CSx to do an address search like a 60C?
