It took me some getting used to. There are actually two sets of Favorite pages - the first set where you can configure up to 6 pages that go through via Round Robin, mixing FM, AM, and XM on them. The second set is a pair of pages that you can have the radio auto-scan for the strongest signals. I used the second set driving across country the last two summers.
I have 6 on the main favorites area and 2 on the scan for the strongest signals. Normally I only keep one page on my favorites - the second page is reserved for the XM stations I listen to when they do their periodic free periods. The car remembers the settings on pages past the first even when you don't have the system set to cycle through them.
