595LM Routing Nightmare

Took my first trip with my 595LM. I used Basecamp for Mac in which I made 6 different routes due to the 30 waypoint limitation instead of using shaping points. I have many years of experience with my Garmin 276c which was flawless using MapSource. My routes have a combination of expressways, state and county roads. Here's my nightmare..... the 595LM kept re-routing making shortcuts any where from gravel roads to two tracks. It "did not" want to stick to my pre-made route. My preferences are shown below. None of this mattered........ If anyone knows what may be going on along with correcting this problem...... Please let me know. Thank goodness for paper maps.

 

Thanks for the help...... I will check the settings on the 595LM. Hopefully that's the problem. Thanks again, I sincerely appreciate the help. Ray

 

I went into the 595LM settings. I did have a couple settings different than what is set in Basecamp, they arte as follows;
Basecamp Avoidances:
Unpaved Road (checked)
Ferries (checked)
Toll Roads (checked)
595LM Avoidances:
Unpaved Roads (unchecked)
Ferries (unchecked)
Toll Roads (Allow)

Other current 595LM Settings
Off Route Recalculation
Automatic (highlighted)

Installed Maps:
595LM myMaps:
CN North America NT 2019.10 Foursquare
North America DEM
CN North America NT 2019.11 ALL

Basecamp:
CN North America NT 2019.11 ALL
Global Map

Not in Basecamp
CN North America NT 2019.10 Foursquare

Even with these few differences, I see no reason why my route is being changed while on it. My routes are consists of major expressways, state and county roads. I'd like to add, I'm still trying to figure out why there is a difference in maps between Basecamp and the 595LM......

 

Thanks for the help..... I did change the differences in which everything now matches. I thought that the 595LM had the same settings. Maybe they were changed due to firmware updates, I'm not sure. I will make sure that they match up from here forward. With that being said, I.M.O. those minor differences shouldn't have caused the 595LM to re-route me when I'm driving on a perfectly routed route with major roads. The 595LM wanted to take shortcuts and it didn't matter how it did it. As far as the maps, what's with CN North America NT 2019.10 & Foursquare North America DEM? It may be an earlier firmware/version. If that's the case, I.M.O. they should have been overwritten during updates. These maps don't show up in Basecamp. If they're not related, why are they there? Thanks again for the help. Ray

 

Thanks..... I basically understand what you are saying. I unchecked CN North America NT 2019.10 & Foursquare North America DEM on the 595LM. Again, I.M.O. It shouldn't even be there. This along with many other reasons I feel that Garmin along with Basecamp is a GIANT step backwards in tech compared to my previous 276c using MapSource. Never, Ever had these issues. Thanks for your help getting me through this. Ray
