Revision: 15 January 2004 (Add Garmin USB and *.gpx Support)
Revision: 17 March 2004 (Version A.00.174 adds USB and serial support for the Garmin 60C)

General:
With Ver. A.00.162, support is added for exchanging data through the USB serial port of the new Garmin StreetPilot 2610 and 2650.  In the graphic below, one must check the "USB" box for those Garmin receivers supporting USB in the units themselves.

While G7ToWin has always supported Garmin receivers, it will also support up/downloading waypoints, routes and tracks of the Magellan M-315/320, Map 330, Tracker, ColorTrak, Map 410, SporTrak (Pro and Color), and Meridian series receivers.  These are the only Magellan receivers verified to work with the program to date.  The same version also supports a number of Lowrance and Eagle receivers

With the above version, if any waypoints are selected before the column is clicked to start the sort, the same waypoints will be selected after the column sort and the list will be scrolled to ensure that the first selected waypoint in the list is visible.  This aids in analyzing the waypoint list.

Note that the file format (*.g7t) has been created.  When you have saved data in this format, and have registered it to g7towin.exe to be the target of *.g7t files in the "Open With, Other, Programs" dialog box, a double-click on the file launches G7ToWin and displays the data.  The program now also reads and writes the new .gpx format (which supports waypoints, tracks, and routes) and uncompressed .loc files.
See:  http://www.topografix.com/gpx.asp

Configuration:
Above is the File, Configuration, General screen.*
*For Magellan receivers, Select GPS (Magellan), then select the COM Port, and Speed (We get the best results at 9600).  Set the unit's baud to 9600 and NMEA to OFF.
*For Garmin receivers, just Select GPS (Garmin or Garmin_USB), and the Speed is selected automatically.  Set the non-USB GPS unit's protocol to the Garmin mode.

NOTE: G7ToWin Help has the unique ability after displaying the Configuration menu to press F1 (or the Help button) to get instructions on how to use boxes in any of the tabs in the Configuration menu.

Icons:
Use the Icon Property tab to further fine tune the data transfer icons.  If you have a Map-330, Meridian series, or SporTrak Pro, set the Icon Family to "330, Meridian, SporTrak Pro".  However, if you have a 315/320, Tracker, ColorTrak, Map 410, or SporTrak, set the Icon Family to "315, ClrTrkr,Trkr, 410, SporTrak".  Garmin receivers have similar selections.

Once you have saved these options, the program should work the same as with the Garmin and Lowrance units with one major exception for Magellans.  Before downloading routes, you must first download the waypoints.

Display on Street Atlas (SA 4 thru 9) :
NOTE: All of the data downloaded into G7ToWin except POIs (see Magellan POIs in the G7ToWin help file) can be displayed on any version of Street Atlas and be configured to one's liking.
Below are some suggested settings to control how the data is displayed on Street Atlas.


SA Route/Track Options tab


SA Text Options tab


 SA Line/Circle Properties tab

Waypoint List:
This list is one of eight dropdown menus on the main page, and is very useful in editing and researching the waypoints.  A feature of this list is that any of the waypoints can be selected as the "Reference".  In the above example, 'COR-NE'  has been selected as reference,  and then the Reference Distance column has been sorted. (In fact, each column of the waypoint list can be sorted.)  The distance to all the other waypoints is then displayed.

Commands:
Magellan: Under GPS, Commands is: Delete All Magellan: Waypoints, Tracks, Routes, Fix, and Data.
Garmin: Under GPS, Commands is: Get Voltage, Get Time, Get Position, Get Supported Protocol, Get and Show Display Bitmap (downloads a screen shot), GPS Power Off.  Also under GPS is: Get GPS ID (GPS name, Software version, Coded model number, Base map Info, and some installed map Info).

G7ToWin (and G7ToCE) will copy the position returned by the 'Get Position' command to the Windows clipboard in the current datum and display format. The fields are separated by the TAB character and may be pasted directly into other applications.
