XM Activation with new 1 year FREE PACKAGE

FYI:   Info if you are getting the 2010's with the SUN ENTERTAINMENT DESTINATION PACKAGE on an LTZ you are supposed to get one year free on XM with one year free of XM-NAV.  Could not get it through the "minds" of XM Customer Service 'cause all they know is "3 free months."  Had to call XM Corporate Customer Relations Dept 877-967-4672 option 3.  There you will speak to "English" speaker and intelligent people.
