Well, there seem to have been a lot of threads discussing the incompatibility of various Garmin units with Parallels, but thus far I haven't seen a single comment from Parallels themselves about whether this is something they're planning to get working. Having re-switched to Mac 4 years ago (had an LC and Vx back in the day) I've got all my productivity programs, utilities, web apps etc. working fine on the Mac. The only thing I still need my PC for is to support Garmin mapsource - so this is the primary reason for purchasing Parallels desktop. Just some indication that this is a problem that's being worked on would be really helpful. Thanks!
