I'm also wondering if it's possible to get the same level of detail on OpenStreetMaps cycle layer into Basecamp and GPS devices themselves
Certainly not easily! I've looked into this myself and the complexity soon overwhelms. I think creating a gpsmapsupp.img file for the device is possible, but so far Basecamp seems unlikely.
Indeed, but not impossible. I've found there are two choices, if you have a recent Garmin unit with BirdsEye, you can use OkMap to generate quick and dirty maps. Being BirdsEye they're not navigable and can be slow, but workable in a pinch.
Second option is to pull the raw data and make real maps. These are the steps I use - they work well enough for me but I've seen countless other ways.
1. Goto Open Street Maps site, find the spot you want, use their export button.
2. Use SRTM2OSM to download topo contours (if you need them)
3. Convert the OSM map data to intermediate Garmin IMG files using MKGMAP
4. Tweak the Garmin TYP file to your liking (map colors, symbols, shading)
5. Compile the IMG files into a Garmin gmapsupp using MKGMAP
6. Upload the file to your GPS, view in Basecamp when GPS connected.
7. Optionally use MapSetToolKit to install your custom map into BaseCamp.
