Sirius will be adding a sports block to its channel lineup when the system undergoes an update today. The sports block will be on channels 162-194.
Here's how it will work: When you turn on your radio, your radio will take 2-5 minutes to update the programming. Once it's done updating, you can flip it to 175. If you can hear audio, you are in luck and you will have the sports block.
The sports block will help keep games together and not preempt the other stations.
Not all radios will be able to handle the upgrade. The Stiletto 100 and Stiletto 10 will not get the update.
