So my wife and I had a 2005 Lexus GX 470 with XM / Sirius and loved it. Sounded great even better than stock FM so I was familiar with the sound. When we traded her 05 in for a new 2011 GX 460 I noticed the sound quality with the XM Satellite Radio was whack! It sounded low and muffled with out the clarity and superior sound quality like before.
So I purchase my CT and the same thing! Thinking I was crazy I have had 2 loner cars from two different dealers lately. A 2011 RX 450h and a 2010 IS 250. Both sounded awesome and reminiscent of our old 2005 GX470 so I knew I wasn't crazy! Further more I had a local car audio specialist to whom the local So Cal XM rep Chris Greenfield also brings the companies car into for XM to be installed and they also confirmed that it sounded whack!
The rep told me Lexus has switched the hardware in some 2011 models and did not inform them of the change. This problem as well as a semi related issue with the nav-traffic are directly related to this according to the XM rep.
I took my CT into my local dealer and he said there is nothing that they can do. That the hardware is fine and that a software update needed to be performed to fix the problem. They said at this time no such update existed. When I said about the quality of the satellite radio was fine in a 2011 rx450h the dealer said that's because they were still using 2010 hardware parts for the radio.The dealer did acknowledge that the FM radio-CD-USB-Bluetooth all sounded great in my car EXCEPT the satellite radio!
Is the hogwash from the dealer or is anyone else out there in CT land experiencing the same issue????
