I just got XM in my Sport and will never go back to AM/FM radio. I've been wanting it for a while but just got the $$ scraped up to do it. I first saw the Pioneer add-on unit at my local Wallyworld for $199+tax not including antenna or install. Went to the nearest Circuit City and they had the same setup for $169+tax. (So much for Wallyworlds low prices, DON'T BELIEVE THE HYPE!) Made an appointment to have it installed and brought it in. As luck would have it, the Pioneer unit was out of stock. So they instead installed the Alpine unit. The nice thing was the Alpine was listed for $249 and they only charged me the Pioneer price! Whoo...Anyway, I told the install man that if he can't make it look like Ford installed it to forget it. He said no problem. After about 1 1/2 hrs he was finished and it looks great!! Not one exposed wire anywhere. Custom install in my console between the seats looks factory. Needless to say, I'm very impressed with XM Radio!! If a person can't find something they like on it, they don't need to be driving....IMHO...best purchase I've made yet for my Sport...so far...
