Hello,
I would like to know if my Colorado will work with the Garmin Birdseye maps that we can download for 29$. Did anyone try this ? How is the map quality vs a vectorial topo map ? I intend to use them for France and Switzerland. Thank you for you help.

A vector map is a database that describes the road network, i.e. the information needed for a route planning system to ‘know’ how to find the route through a road system."Vector" maps display digitized information. In other words, every depth,they allow the user to display "layers" of information .A vector map is a lot faster to scroll, zoom, get particulars.vector maps are easier to read.

A raster map is a picture. It gives only image information.A raster-scanned electronic map is like an electronic snapshot of a paper chart. On-screen it looks just like the same familiar paper charts you've used for years. If you're using a color monitor, you'll usually see the original colors from the paper chart.

Raster charts in any orientation but "north up" (or whatever matches the original raster chart orientation) are not readable because text and labels are pointing sideways or upside down. Vector maps can be rendered with text and icons "right side up" regardless of course and chart rotation..
