Won’t load routes to zumo 660 or 665

I’ve used BaseCamp ever since it came out for the Mac, and I’ve usually been pretty happy with it. But this BaseCamp update combined with the system software update on the Garmin zumo 660 & 665 motorcycle GPS systems no longer works. I reported this to Garmin, and they confirmed in a letter:

“Due to product testing that has occurred it has been determined that the [sic] BaseCamp is not compatible with transferring created routes to either a Zumo 660 or 665. This is likely [due to] the latest software update which was released in 2014. The best option at this point would be to either go back to using RoadTrip on your Mac, or to download Garmin MapSource on a Windows based PC.”

No mention of whether they plan to fix this or not.
