Query: Worst Topo Maps Available?

I purchased the Magellan SporTrak Topo GPS with MapSend Topo software. The topo maps are almost useless. The first thing I did was load the software on my PC and went to maps of areas where I am very familiar with the terrain. One creek near my home in California is at the bottom of a canyon with at least a 200 foot drop in elevation from the road above, but appears on the "topo" map to be on level land. Another map in my favorite hunting area in Wyoming shows a "road" and 4WD trails where only horse trails exist. My house appears on the wrong side of the freeway. These maps could get someone in real trouble.
