Hi, I've just discovered that a directory called .Spotlight-V100/ on the microSD card makes my Garmin Legend Cx crash when I switch it off. The crash leads to a continuous beeping sound, and the only way to stop it is to remove the batteries (and external power if connected to USB.) The .Spotlight-V100/ directory is created if you mount the micro-SD card on a Mac; apparently spotlight carries on to index the files on the card, thereby creating the directory. I have not investigated if you can turn this behaviour off. By "mounting" I mean setting the Garmin device in "USB-mode". The .Spotligt-V100 directory is _not_ created if you connect the device to the Mac and use Garmins programs (such as RoadTrip) to communicate with it. If I delete the directory in question, the very annoying crashing behaviour stops, and the Garmin switches off with the normal two-note beep. Cheers, Morten
