My 2006 TL is suddenly experiencing a problem with the SiriusXM radio display and audio. Occasionally the sound won't come on despite repeated button pushing or change channels once the sound comes on. The latest is the disappearance of the title/artist display either in the navi screen or in the area between the temp and time display at the top of the instrument panel. Any suggestions on what to tell the dealer when I take the car in for other issues? The car has 86,000 miles and a 3-month old battery. It stays garaged at home and at work.

 

Did you ever cure this issue?
