I have a 2005 ES 330. recently the Sirius radio service stopped working and the word "Antenna" is flasing on the radio. I have taken it to the dealer and have spoke with Lexus customer support. they have advised me that they no longer can get parts for a Sirius radio and I would have to install an XM reciever if I want to have satellite radio. Has anyone else had this problem and were they able to resolve this without installing an XM reciever?
