How to upload KMZ paths?

I just purchased a 700i as my first handheld GPS. The primary purpose is to find old abandoned rail lines that I have mapped with Google Earth and then exported as KMZ files. I converted the files to GPX format and uploaded to the 700i in the GPX directory. I cannot get these paths to display. Google Earth placemarks will display as waypoints but I cannot get Google Earth paths to be visible on the 700i. As a newb to Garmin, I'd appreciate any advice.

Hmmmm. . .I do this all the time without any issue at all via Garmin Basecamp on a Mac. I draw paths and create waypoints in Google Earth. I then save the info I created as a .KMZ file(s). I File/Open in Basecamp. The files show up in the Recently imported List. I then move the stuff to the List of my choice. When it is all organized and labeled/colorized how I want I upload it to my Garmin. This has worked for me for what? 15 or more years?
