Yes, due to a slight miss this is a bit more complicated than necessary, you currently have to make two changes in two files. This will be fixed in the next release.
* Open GpsGateServer\VehicleTracker\GpsGateOnlineScripts\GpsGate.VehicleTracker\vehicletrackermain.js
In method "initUIComponents" (line 99) you'll find the line "this.m_initMapControl();" (line 103).
- Change it to say "this.m_initMapControl($('changeMapType').checked);"
* Open file GpsGateServer\VehicleTracker\VehicleTracker.aspx
Change the checkbox to be default unchecked.
line 148: " <input type="checkbox" name="franson map" id="changeMapType" checked="checked"/> "
- Remove the " checked="checked" " part above.
Now, GMap should be the default.
As said, in the next release you should only have to perform the second step. In future releases we aim to create a more user-friendly setup page where this kind of settings can be controlled.
