What is your common workflow to plan a trip?

Hello Everyone,

I'm a brand new user of the Montana700. My original intention was to use this for deep woods hiking and for longer distance motorcycling. The user interface is not exactly what I expected and the device is very cluttered with many little Apps. Took me 5 hours to finally get used to some of the tools and created a test Route on the device. Then, I found out that the Route wasn't snapped in corrected at every single part of the road. 

So, I had to manually check the entire Route on BaseCamp to make sure the pink bright Route is correctly snapped in.

Seems like there should be a better and more automated way to do this. I'm sure I'm not doing this correctly.

Looked at the User's Guide on Garmin website and the steps had dependencies, like the already setup Waypoints and what naught.

Question: Is there a trusted place to look for clear instructions on how to ramp up the learning curve?

PS: Just so you know, I come from a technical background (Computer Science).
