GPS on Great Divide

[tacticalathletes]

Purchased an Etrex30 with my REI dividend.  Downloaded a couple tracks and a route to test navigation over the weekend. Nothing but headaches up to this point.  I was guessing something close to what google maps does for us on a smartphone.  The tracks and routes show up on basecamp fine but on the etrex the route is covered in flags and data obscuring the route.  I've read the user manual and googled various help on this all day yesterday.   Starting to think about returning the unit and just going back to good old map/compass and cue sheets from ACA.  

Advice or experiences?

I have an older etrex so I can not give specific answers but I think you might try some combination of:

1st eliminate all the route data but the gpx "track" file

2nd turn off all forms of data but the track

3rd zoom in further
