Got a '12 TL a week ago and I'm trying to learn how to use everything. Playing around with XM today; my first car with XM. I can't find any way to display a list of categories, or to display a list of the stations within a category. It seems that the channel list is all channels, and that you can't just drill down to the list of channels in a particular category. It also seems that you can switch categories using the Category +/- button, but not show a list of them. I'm just posting this in case there are any undocumented tips to do these things. It seems weird not to have these obvious display options. Thanks for any help.
