Last week I asked about how to find the XM ID on my 07 LTZ, which has the nav system. Another user told me " channel 0 or1 should give you the radio ID"... but I don't have a way to enter a specific channel number, that I can find. My XM display shows channel up/down arrow buttons and the category button, and it's limited to the three default XM stations (emergency, sportsbabble, and POTUS). What am I overlooking? (Sorry, the separate nav-system manual didn't come with my truck, it's on order, otherwise I'd just RTFM.)

Thanks!

(And here's hoping Sirius produces a SiriusConnect integrated tuner for 2007+ GMs like their Class-2 Bus system for everything through 2006...)

 

By the way, if anybody is interested, I did some poking around this morning and apparently Directed (the people who make a lot of the Sirius in-car interfaces) did show a 2007+ GM-LAN compatible interface at CES. They said it would be available in the spring but it isn't out yet. It'll be called GML-SC1 (whereas the older non-compatible version is called GM-SC1).
