I just bought a 2007 nitro slt have a free 3 month subscription to sirius radio. I wet to set it up and the sirius website said it is an eligible radio. But when I put it on radio all I get is a screen that says to call sirius and an 888 number. I've talked to them and they gave me the radio id. (018027946431). I've tried their refresh link and it says to put it on channel 2 but I can't make it do anything when I put it on satalite.
