I've recently purchased a Sportster 5 Sirius XM radio and due to an unforseen anomoly I have to sell it. It comes with the receiver and complete car kit along with a one year subscription of the mostly music option. I bought the radio and car kit for $170 from Radioshack and the one (1) year subscription for $150 ($320). I will let it go for $200 plus shipping to your zip code.
Keep in mind it's not even 4 days old.
I hate to get rid of it but sometimes you just have to.
