i've had my acadia for less than a week, but i've noticed that when i go into the xm categories, that more times than not, all the categories are not displayed and all the options within categories are not displayed. you can tell by the sliders on the right and left. sometimes this works fine, other times you just can't see all the xm categories and/or channels within each category. i'm new to xm, so i called them and asked about it. their response was to contact the dealer; you should get all the categories and channels right away with no delay.
i've checked the setup many times; my unit is definitely setup to receive everything.
