GMX200 not displaying FIS-B weather from GTX345

[Wallis]

We have the GTX345 transponder connected to a GNS-430W and the GMX200 MFD t in our Bonanza. ADS-B/FIS-B weather and traffic was displaying perfectly on the GMX200, then, the plane was down and battery disconnected for about 5 months for an engine overhaul. Ever since getting everything put back together, FIS-B weather will not display on the GMX200 and all the status pages show "Not Available". Traffic still displays properly on the GMX200, though. Both weather and traffic display normally on the GNS430W, so I know the weather is working. Here's a screen shot of the com port setups on the GMX200 (which shouldn't have changed since before the overhaul) and the weather status page, which shows there are data coming through for ADS-B. The GDL69 on port 3 is providing XM radio (audio only, no weather subscription). Any thoughts/help appreciated to try and get ADS-B/FIS weather back on the MFD?.
