Gary:
Since it appears you have the I/O working, to receive live ADSB weather you'll need,
1. To be at sufficient altitude to receive a ground station.
2. Set up AVARE as follows,
Touch the icon directly above MAP, at the bottom left, on the map (home) page.
Touch PREFERENCES, top box in the left column,
Touch Weather,
Touch SELECT LAYER TYPE, and touch 50% or opaque, depending on your preference.
Touch USE ADSB WEATHER,
Touch your phone/tablet BACK icon two times to navigate back to the AVARE map (home) page,
Touch the icon directly above MAP,
Touch the NEXRAD, or METAR, or NO LAYER, the second box in the right column, and touch NEXRAD,
Touch the map to clear the settings options.
You should now be set up to receive ADSB weather.
The weather will display similar to this image from the AVARE site on GOOGLE PLAY
VFRs,
