My unit is acting up. Everything is working fine (Ipod,bluetooth...) but recently out of the blue the Sirius interface has stopped working. It's like it's froze. The screen looks normal but none of the buttons respond and there is no audio?? This only happens when trying to listed to Sirius. AM, FM, Ipod, bluetooth all work normally...

Help???

Thanks

well what model sirius unit do you have? loose ip bus cable? bad antenna? need more details
