I would like to convert the Arizona topo map for use on my laptop pc with my gps receiver for real time navigation with one of these: the Trackmaker program (.gtm, .gtz) or a mapdekote file (.dbx) or ArcGIS shape file (.shp). The receiver mfg isn't relevant since it works with the pc and Streets and Trips and Google Earth- there is no problem there. I also have gpsGate.   I do have a Garmin gps but want my wife/copilot to have a larger computer screen when we're driving in the car. Don't want to use GE.
I have loaded the Arizona data into my hand held Garmin gps- screen too small.
Streets and Trips works but I want the option of using other programs.
The Arizona data comes as an "install" file, unknown type.
I might be able to convert this file with gpsBabel but don't know the "install" file type.
Can I do this or is this file only for a Garmin install? thanks, Gary
