TrackRoad.com can import your optimized route directly into Garmin nuvi without 
                the help of any other software. In this example, we will use Garmin nuvi 760 but 
                this should work on any gps device that supports GPX file format.  Please note that some older model Garmins may not support importing of GPX files. 
                Please check owner's manual when purchasing the unit.
                
             
         
        
        
            
            
                
                    Step 1: Connect the USB Cable
                    Connect the mini-USB connector to the bottom of the nuvi. Connect the larger end 
        of the cable to an available USB port on your computer. Your nuvi and SD card 
        appear as removable drives in My Computer on Windows computers and as mounted 
        voulmes on Mac computers.
                
             
         
        
        
            
            
                
                    Step 2: Build your route in TrackRoad.com
                    Uncheck both "Include Maps" and "Include Directions".  Directions will be 
        provided by the Garmin and unchecking these options will make generating route 
        alot faster. Click the "Build Route" button.  Please remember that the number of 
        stops that can be imported maybe limited by your gps device.
                
             
         
        
        
            
            
                
                    Step 3: Save the route as a gpx file to Garmin
                    Assuming that you have built your route in TrackRoad.com, go to the Get 
        Directions tab. Then click the "Garmin" button on the right.  A dialog box 
        opens, cick the "Save" button.
                
             
         
        
        
            
            
                
                    Step 3 (Continued): Saving the route
                    Browse to and open the Garmin or SD card drive/volume. Open the Garmin folder 
        and then open the GPX folder. Click "Save" to save the "WayPoints.gpx" file.  
        Unplug your nuvi from your computer.
                
             
         
        
        
            
            
                
                    Step 4: Getting nuvi to see your route
                    Start your Garmin, go to Tools, My Data. You should see "Import Route from 
        File".  Touch "Import Route from File" to use the route you imported.
                
             
         
         
        
            
            
                
                   Go to "Where to" in your Garmin and select the route you just imported.
                Enjoy your trip.
