    good day- My 2001 GS300’s radio stopped working. I checked the vehicle fuses and all are fine. I’m just trying to figure out it there is another fuse on the actual radio itself.

    came across this site in search of any ideas on why and how to fix my GS 300 2001 Lexus radio. It just stopped working all together. I had the dealership and outside source confirm it was the stereo itself. Any ideas on fixing or sending to somewhere to be fixed? too expensive for a new one.

    Bridget, it would be more cost effective to just replace your faulty radio with an aftermarket radio.
