Has anyone looked into the mini XM radio that works as a portable w. 4 hour memory? The XM direct is 50 bucks, then it looks like you need another 50 dollar adapter. For 300 you get the portable with home and car kit... is there anyway to get song info via one of these things? I change vehicles a lot and the XM Direct thing might be a hassle compared to a portable... I wish you didn't need a subscription for each device you own. It'd be nice if only one could work at a tiime.
