I'm trying to navigate real time with an USB GPS over a shapefile map, but I can't find the way to do this. I'm using QGIS 1.9.0 desktop version with a Garmin Etrex Legend HCx GPS.
In fisrt place, QGIS doesn't recognise my GPS port. In addition, I cannot find in QGIS the option to navigate real time.
Do you have any idea to help me with this?
