Is there a way to reload the XM channel logos? Not all of mine downloaded when I first initialized my XM subscription.

They do not download. They are installed directly on the hard drive. Forum member Vandal has done some upgrades that will fix the missing logo's, but you will need to either 1. Unlock your stock drive, or 2. Have a drive that is already unlocked.

See this thread in the XM group:
