File limitations of the fenix 5x?

Found this online. It says it doesn't support the ability to add maps, but I'm pretty sure the 5x does support that.

[h=3]File Limitations of Garmin Outdoor Wearables[/h]
When sending or creating files for an outdoor device, keep in mind the following device limitations:


D2 Bravo, fenix 3 series, fenix 5 series, quatix 3, tactix Bravo

• 1,000 waypoints
  
• 50 routes, 250 points per route
  
• 100 saved tracks
  
• 10,000 points per track
  
• Unlimited points per fit file (limited only by storage space available on device)
  
• Ability to add maps unsupported
  
• Connect IQ supported (watch faces, data fields, widgets and apps); Connect IQ apps may fill available internal memory before file limitations are met
  

Each GPX file can contain a mixture of waypoints, geocaches, routes and tracks. If the GPX file containing a waypoint or geocache is deleted, the waypoint will no longer be available on device.

When utilizing routes, only 50 points can be used for on road navigation.

Thanks!

Has anyone tried uploading tracks with more than 500 points into their Fenix? I tried with Basecamp to upload a 700 point track, but it gets reduced to 500 points on the watch itself?

I am not able to send any data (favorite or track etc.) via basecamp to my 5x+.
