2015 Lexus GS 350 Sport radio/navigation control functions locked up.

What is your question?

I have a problem with my 2015 Lexus GS 350 Sport. Yesterday on a 140 mile drive, the radio locked up and I was unable to raise/lower volume, unable to turn off the radio or control navigation. The steering wheel radio/phone functions would not respond either. I got home, turned off vehicle and restarted it and everything worked ok. I have only driven the vehicle once after the incident and everything is ok so far. Vehicle only has 19,500 miles. Are others experiencing this condition and heard of a fix?

What makes this problem better or worse?

Has happened only once.

How long has your 2015 Lexus GS350 had this problem?
