I bought a Garmin Edge 800 this past weekend. I went through to Garmin this morning and bought tracks4Africa version 13.05. This was recommended for better detail off road. My problem is that when I start the unit up at home it does not show a lot of the roads around my house. If I drive around it does not show a lot of roads. A lot of the roads it does show it does not show road names. Does this sound right?
