Is there a new estimated time for the display of the new data available from ADS-B (eg. lightning strikes)? When this happens, I believe I will be able to stop the XM downlink service.
Last I read (here) it was not planned to be in the next software release but, at the time, that release was expected by EOY 2018. Hoping they get it in 15.3.5 too.
Won't be in the nearer release (which more primarily supports certification changes), but will be in the next feature release. We don't have a date estimate on it yet.
