Darn shame Magellan discontinued ther Meridian series, they were a great GPS units at one time. They should have simply updated the software/hardware with the Meridians instead of discontinuing them for the Explorist.

Here is a photo of how a Garmin color units looks with topo software.



I know that that the Garmin topo does have roads, rivers, and such also. Both Magellan and Garmin have a simulator online that will show approx what level of detail of map you are going to get if you buy the topo software.

I agree with the others, for bicycling, get the topo software regardless of the unit.
