Basecamp has replaced Mapsource as Garmin's default  mapbrowser and has some nice features like 3D (not available on Openfietsmap, choose in Map Views 2D map - Ctrl+2), better track management, filtering road or waypoint types and better elevation profiles. However, routing is only compatible with the latest GPS devices (Etrex 10/20/30, Montana, GPSmap62/64, Oregon x50, 6x0).

Garmin does not update Mapsource anymore but the software can still be used and is recommended for older pc's in combination with older gps devices.

Driving will avoid semi/unpaved trails, in the activities Bicycling/Tour cycling Toll road avoidance (will route on bike routes, see below) is unfortunately not available in this profile. Activity type Walking will ignore oneway streets which can be useful in cities. Hiking will do the same but here are Interstates/Major highways selected and greyed out (interstates/major highways are cycleways and -routes on OFM)

Routepreference:

• Shorter Distance
• Faster time (prefers cycleways and -routes)
  

Road Type Avoidances:

• Never avoid major highways because the cycleways are the major highways!
• Residential roads: avoid footways/forest trails
  
• Unpaved roads are also gravel compacted bikepaths

Feature Type Avoidances: 

• Nothing selected (except cable cars/climbing paths, they have no function on OFM);
• Toll road avoidance will prefer routing on bicycle routes,
  
• carpool lanes avoidance have no functionality anymore

Some recommended profile settings

Regular cycling

• This type of cycling will  seek the cycle routes, to select this one needs to set toll roads avoidance on.
• This is not available in the bicycle profile, so you need to use the motorcar or car profiles:

• Use this activity for cycling in cities (ignores oneway traffic) , walking, horseback riding etc
• Most bugs in older versions (not routing across map tiles, unroutable bridleways) are solved.
