I've been interested in getting XM lately, but the only reason I would get it is if I can get a portable device that receives XM live. Apparently this is available in the Pioneer Inno. With this thing it can work in the car or on the go with head phones. The problem is I've been reading a lot of reviews that shun the reception when on the go. Apparently it's a hit and miss and when in buildings with no windows or a lot of trees it's a no go. I just wanted to see if someone has experience with this or opinions on this. If the portable reception isnt worth it then I'm not even going to bother with it. Thanks.
