Can't remember now-as it's been a while since I looked- if it's possible to copy/paste onto the CRN using a computer/laptop like you can with Garmin. Think the best option-and probably the preferred one as it keeps everything synced - is to use the connected ride app on the phone. Under the "3 peaks" routes tab if you then click on the right hand tab within (with the pen icon ) there is an option to do a route import which opens the file manager on the phone. I usually save the file to cloud storage and copy/import from there, but as with a computer you could probably paste the file to a saved location on the phone and use that route as an alternative. Hope that helps though I'll admit it's still a learning curve for me and others might have better suggestions.
