I'm having same difficulty. Installed Keyspan OSX driver, and MBP "sees" the adapter in the Keyspan application window. Likewise, green led on adapter is flashing, so I assume it's communicating well w/ MBP. However, when I hook up the garmin 182 gps, nothing. I know the gps is outputting properly, as it's lat/long is showing up on screen of vhf radio, also connected to the garmin output. So, I'm assuming the problem is not in the output of the gps. Is this controlled from the Mac or the gps?

Thanks
