I know this doesn't solve how to get the Garmin stuff to work with Parallels, but Garmin did have a press release early this year indicating that they would have support for just about all of their products by end of year on Mac, see http://www.garmin.com/pressroom/corporate/011006.html It looks like they are behind schedule, but I would suggest as many emails as possible to Garmin to ask them when they plan to release their software on Mac OS. This might turn out to be faster than Parallels support ?
