2015 Midnight Edition radio "upgrade"
Is there an "upgrade" that can be done to the XM radio system in my 2015 Silverado Midnight Edition? I heard that SiriusXM were using channels numbered 300+. My wife just purchased a Cruze and I noticed that her XM radio goes up to 400+ channels. Just curious if there is an upgrade available to my radio, a rough estimate on cost, and possible sources other than dealer.
