SIRIUS™ Travel Link™
The SIRIUS™ Travel Link™ is a subscription-based service available on vehicles equipped with navigation. The satellite radio antenna receives digital signals containing Travel Link™ data. These signals are routed to the satellite radio receiver (integral to the ACM) from a splitter that is part of the GPS antenna coaxial cable. The satellite receiver decrypts the data and the ACM sends it through wired circuits to the APIM.
Certain date-dependent features (such as sports schedules and scores, movie times, or the 5-day weather forecast) require the use of GPS data for accuracy. The APIM processes the data from the ACM and sends it to display on the touchscreen. The time intervals for each Travel Link category to update the data vary, depending on the category.
