Hi,
I am having a problem getting the Navaid (complete with smartcoupler) to talk or communicate with my satnav. I know the Avmap is sending out the correct NMEA strings because I have a Dynon D100 and the data from the Avmap flight plan is overlaid in magenta on the Dynon HSI.
The unit works OK in wing leveller mode to the AP1 isn't the problem.
Navaid have asked me to check the wiring from the Avmap, which I have and I have continuity, a ground and a signal from the satnav.
Has anyone had a similar problem or can you provide any suggestions?
Navaid have said I may need to sent the smartcoupler back to them in the States, but only as a last resort.

Have you checked that the NMEA strings contain all of the required data?
The NMEA protocol allows data elements to be missing, so long as the comma
separators are still present (so that the absence of the data can be
identified).
So, for example, the cross track error data can be omitted, but the rest of
the sentence is still useable. But I wouldn't have expected this on an
aviation set.

Hi Duncan,
The Avmap has a check list box that you just tick to ensure that string is included or excluded. The Dynon strings include the two that Navaid advise need to be present for their equipment to operate in course mode.
