NMEA strangeness from Garmin 60C GPS
I have a Garmin 60C GPS which I have tried from time to time to interface with a DSC VHF radio or Raymarine wheel pilot but the other devices act as if no NMEA sentences are being sent.
I've tried it with a Raymarine 54 VHF, S1 Wheel pilot, and a Standard Horizon Matrix VHF and none of them recognize the Garmin GPS.
But when I connect the 60C to my laptop, it happily connects as expected at 4800 baud and both OpenCPN and Google Earth can recognize and use the NMEA input just fine.
I've tried *three* different Garmin cables, and two of them were also tested with my old Garmin 12XL and work just fine, so the problem isn't the cable or the connections. Unplugging the 12XL, which the VHF and autopilot recognize and plugging in the 60C still fails to work.
Here is an extract from the NMEA output from the 60C:
I'm wondering if it is a versioning issue. Perhaps OpenCPN and Google Earth support a broad range of NMEA versions and the VHF and autohelms I've been trying to interface with don't. But certainly the old Garmin 12XL has a much older version of NMEA, so why would it work where the 60C would not?
I'm left scratching my head.....
Any NMEA gurus with some insight?
