Reset GPSMap496 and PAW awaits GPS fix

[grvbc]

I've got a "fixed" installation with a Garmin GPSMap496 feeding fix data into the PilotAware via a USB-serial adaptor.  It's worked brilliantly and reliably for some time.  Love it.

But,  after many years of use I'd filled up the GPSMap496 with routes and waypoints etc, and it was displaying some peculiar behaviour... so I reset it back to factory settings and set up the serial interface as it was before (TIS in/NMEA and VHF out @ 9600 baud.)  Now the PAW isn't getting satellite fixes, although the NMEA log shows the NMEA $GPRMC messages coming through (along with loads of $PMRRV radio messages).... see attached.  Any suggestions?

As an aside, I can only sometimes get a response from requests to the 192.168.1.1 administration webserver  too...   but that may be a side effect of no GPS, therefore no fix, therefore no radio startup, therefore....

I feel a twit.... because PAW was working fine, but I needed to reset the GPS.  Tell you what though - I REALLY missed it during my last flight.....made me realise how good it is!

Hi

I suspect in your settings in the GARMIN, there is some way of configuring the NMEA messages which it supplies to PilotAware.
and it looks like you have lost that configuration, the messages we expect are :

GPGGA
GPGSV
GPRMC

Check your manual, you must have configured this previously

can you also post images of the HOME, and CONFIGURE pages

Thx

Thanks Lee

Your advice pointed me in the right direction....and eventually I found the problem; There's an obscure Advanced NMEA settings menu of the 496 where  NMEA GSA and GSV are switched off by default.  're-enabling that ensured all the correct messages are sent to PAW.

So .... All working again now.  Very Happy.
Thanks again.
