Yah I know what your saying. When Mainaic1957 said he loved the autorouting on his 60cs I told him he was crazy and that It didn't auto route. I thought that mine was broke at that point because my 60c won't autoroute. I have topo usa for mine and topo does not autoroute. It shows the feature on the gps but it doesn't not work right. Anywhere you are it will just send you to the interstate no matter where you want to go. So it's all about the software. So if you want autorouting topo usa is not for you. If you want elevation more that auto routing such as I than topo is awesome.
Good Luck
