Direction needed - 2010 RX350 "ghost in my radio" problem

[Agent 337]

Good afternoon.  New member here.  I inherited a 2010 RX350 a year or-so ago and in the past 6 months have begun to have issues with the radio turning itself on, and intermittently changing stations or modes all by itself. Seems like its happening on bumpy roads. As-if something is loose in the stereo or the steering wheel. A month ago, the battery died and needed replacing.  I was hoping maybe the radio problem stemmed from a batter low-voltage situation but a few days after replacing the battery, the ghost in the radio returned. 

The searches I've done on line leads me to believe Lexus had a problem with that vintage sound system (not the Mark Levinson) but I haven't been able to find much info on the cause of the problem, or the fix for it. 

If there is a thread on this issue in this forum, hoping someone can point me to it and I'll take it from there.  Some of the searches I've done here so-far looks like this place is a wealth of knowledge.  I look forward to browsing, and learning more about my vehicle.  

 

Thanks!
