updating the basemap shouldnt affect your speedcams displaying, probably you deleted .unl files
do you have them in your POI folder?

This is the latest DEM (Digital Elevation Model) routable Basemap, it will update your preloaded one, but not necessary to update it IMHO
[Only registered and activated users can see links. ] read post 3
DEM are for displaying shadings on terrain
The standard map coverage includes: (but it depends on regions)
Oceans, rivers, major streams and lakes (greater than 5 sq. miles)
Principal cities and urban areas, with many smaller cities and towns
Major interstates, principal highways, and State/Province level roads
Political boundaries (state and international borders)
Major Airports
Railroads

Yes, that's where I started.
Garmin will reload the basemap, only not at the local representative. This means the unit must be sent to the US and back. Customs paperwork and shipping/insurance costs stimulate me to delay until someone goes that way. Meanwhile I looked for a possible alternative here.

Thank you very much for trying!

Do you think I could/should use another worldwide basemap, like the Garmin Worldwide Autoroute DEM Basemap NR 5.00?
The satelitte imagery was very low resolution anyway...
