Use Garmin's Basecamp as...

If this has already been addressed, a pointer would suffice. My ‘google-fu’ isn’t all that. My question is, is it safe to assume what I see in basecamp, a reliable gauge, as far as what I would see on the Garmin device itself? Meaning, if a label is displayed a certain way on Basecamp, is that what I would see on the device itself? At the resolution/level I’ve built the map with, using mkgmap.

Thank you,
Steven

Typically the different Garmin devices do not behave the same way, esp. not regarding rendering of POI.
