GS300 Sound system

Marchant · June 9, 2018

Hi Guys,

I have a GS300 2005 SE-L. My sound system started switching off when the weather is hot and now it doesn't work at all.

Is it a case of buying a 2nd hand head unit and fit it myself or is it more complicated than that?

Thanks in Advance,

Marchant

Is it the head unit switching off or the amplifier?

The power switches off and the display say audio off.

do I need a security code when I replace it or is it just plug & play?

I would check the radio fuses and the connections to the back of the head unit first.

Thanks Neil, I will try that first. Have a good day. 😀

I had a GS430 a few years ago but unusually for me, I left the audio alone so I've limited experience with it. I did read elsewhere that it is possible to use voice command to turn the head unit off accidentally. Club lexus may be able to help otherwise disconnect the negative Battery lead for a minute or so to reset everything. If it really is temperature related it might me worth consulting an audio electronics engineer....if you can find one.

Does it still load and eject CDs?
