For each enabled SiriusXM Weather product which can be shown as a map overlay, the system displays a
weather product icon and product age. The product age is the elapsed time (in minutes) since the weather data
provider compiled the weather product. The product age display does not indicate the age of the information
contained within the weather product, which can be significantly older than the displayed weather product age.
The SiriusXM Weather service broadcasts weather products at specific intervals (defined in the Broadcast
Rate column in Table 6-1). If for any reason, a product is not refreshed within the Broadcast Rate intervals
(see Table 6-1), the system removes the expired data from the display, and shows dashes instead of the product
age. This ensures the displayed information is consistent with what is currently being transmitted by the
SiriusXM Weather service. If more than half of the expiration time has elapsed, the color of the product age
changes to yellow. If data for a weather product is not available, the system displays 'N/A' next to the weather
product symbol instead of the product age.
Table 6-1 shows the weather product symbols, the expiration times and the broadcast rates. The broadcast
rate represents the interval at which the SiriusXM Weather service transmits new signals that may or may not
contain updated weather products. It does not represent the rate at which the weather information is updated
or when the Data Link Receiver receives new data. SiriusXM and its weather data suppliers define and control
the data update intervals, which are subject to change.
