What do the different Radio States indicate on an XM system?

Below are brief descriptions of the different Radio States that may be encountered with an XM system connected to ForeFlight:

Activation in Process: The receiver is in activation mode and is activating.
Initializing: Occurs when Mobile Link is first powered up and communication is being established.
Online: The receiver is online and receiving data. If the Radio State is not "Online," activation or a refresh with Sirius/XM may be needed.
Reset in Progress: This happens when the receiver is attempting to activate or when a soft cycle is received (which occurs every 30 minutes after all data products have been received).
Unknown: Occurs when the receiver has been unplugged from the Mobile Link.
Weather Data Received: Check that the weather data ages are current. If not, wait for the update.
