JUNE 16, 2006: THE XM SOUND QUALITY PROBLEM HAS BEEN FIXED BY TOYOTA
Toyota has released a new head unit for the FJC that will fix the XM radio sound quality problems. I had my new head unit installed today and the XM radio sounds much better. You need to have your dealer order you a new head unit with the fix. I looked at the old head unit and the new head unit and they had the same part number, so I don't know how they distinguish which head units have the fix. I assume that your dealer or their Field Product Engineers will be able to tell. My head unit was replaced under warranty, so you should not have to pay for this to be fixed.
