Yeah, I neglected to mention that the Cardo syncs seamlessly with both my Garmin and my bluetooth phone. In memory, the only call I actually ever took was a unwelcome cold call from a Shanghai property agent, which is a perfect testimony to why I usually keep the bluetooth function on my phone switched off. And when the Garmin is comfortable with my route, it's sometimes useful to have the Garmin Lady assist with turns. The downside, as you've already noted in another context, is that when Garmin Lady is confused about your route it can get very tiresome to hear "recalculating..., recalculating..." at every turn. So I tend to use the GPS in a passive mode -- just displaying where I am -- while I reference a paper map slipped into the map pocket of my tank bag.

Apologies to non-Americans for the following cultural reference, but Garrison Keillor had a fun segment of Guy Noir conversing with Garmin Lady while trying to get out of St Paul to the airport. Not a huge fan of Keillor, but this was hilarious.
