Hi. Whenever I start my lexus gs300h 2013 the audio is not comming on. The radio, display and everything else comes on, but no audio. I have to drive for about 20-30 minutes before audio kicks in and it fuctions as it should afterwards unless I switch the car off and leave it sitting for half an hour or so, then I have to wait for another 20 30 minutes for the audio to come back on. It seems that whenever the car goes in to sleep mode it disables audio and then takes forever to come back on. Any idea what could cause this delay? Other car forums suggested their problems were related to relays sticking/delaying to open... But I could not locate a relay that would be related to the amp or audio except from 2x30A fuses that were fine. Any help would be greatly apreciated especially from my 2 year old boy who at the moment thinks that it is me who is not switching the music on.... It would save a lot if tears and stress! Thanks!
