My RX 350 suddenly lost all its sound, radio, CD, navi and bluetooth. In the last couple days, I get the sound in the morning, but nothing in the afternoon. I don't think it is the amplier, becasue I do get sound sometimes. I am wondering if it is the heat because I park outdoor during the day.

Anyone else has similar experience?

TIA

 

Still have the OEM battery? Could be getting weak. When it does, strange things start happening. Have it checked by the dealer. Could still be under some warranty depending on your inservice date.
