I've got a 2013 RX 350 and the radio is giving me fits!! About 3 years ago the radio after being on for 1-3/4 hours would start to lose the stations intermediately, then after about 10 more minutes it would lose all station reception and start to hear squelch sound coming out of the speakers. This went on for about 1 year and then cleared up with no further problems. This winter the same issue returned except that it starts doing the same thing at 1 hour & 22 minutes exactly. If, I turn the radio off for about 1 hour it will resume playing and start the same problem over. The CD works fine and I have no issues with the navigation system. Has anybody out there ever had the same issues and know the remedy. Hopefully, its not the amp overheating.
