@Rob-van-Dijk-1 Not using MRA But you may be able to do it using these tools. I have a Zumo XT and these work.

Its a bit of work but it is doable. Basecamp and Garmin POI loader for handling POI's are feature rich but more work than MRA. I'm hoping that MRA improve POI handling with the update to the website.
