Dropping Custom Routes

I'm not sure if this is a BaseCamp question or a zumo question. When I create a custom route in BaseCamp using waypoints, and transfer it to my zumo 660, during the ride the zumo will periodically spontaneously recalculate and say, "Cannot calculate the route. No roads found near the destination." and it drops the route. I can pick up the route again (Where To, Custom Routes, etc.). It seems like it does that every time I am approaching a waypoint. BTW, I use both Mac and Windows BaseCamp, with the same results.

Garmin Support gave me this advice:
1. Reinstall the operating system
2. Do a hard reset on the zumo.
3. Delete the temp.gpx file from the zumo before transferring the new route from BaseCamp.
4. BaseCamp and zumo 660 are not really compatible when using intermediate waypoints; here's a list of zumo devices that are compatible with BaseCamp. (Really? I mean, it's not like I paid $600 for the software and just have to find a cheap GPS unit to go with it. It's sort of the other way around.)

Has anyone else experienced this problem?
