I have a 2016 GS 350. It has developed the following problems; when connected to my i-phone, it is intermittently turning on and off and reconnecting Unable to turn the radio on or off without pressing the radio knob with a lot of pressure and for several seconds. The LCD also freezes unexpectedly. I have upgraded the software by the dealership to the latest edition. Thank you. If this has been addressed somewhere, please direct me to that forum MO KENNY
