With OnStar currently unavailable to order, even people that see the benefit aren't able to place it on their orders. That could be the reason. I hope when it is available, people add it to their orders.madmac9 said:
Those who are unsure of what XM can offer, there is a free trial on-line that you can check out. http://xmro.xmradio.com/xstream/index.jsp Something I always find funny is that one of the great benefits to XM is the lack of commercials on the music channels (XM radio promos are there). In GM, Xm is considered part of the OnStar group. On Star is the largest radio advertiser in the US.
