So the radio is not working as per usual on is250 from 2010 like mine.
I've read through a lot of forums about fixing the radio problem but they all seem to be amplifier or fuse related. Well after drying my amp and then trying it out, then replacing it still didn't work. Then I checked and replaced some fuses and it still didnt work.

Symptoms:
The audio will not play for anything at all. The power on button does nothing. The volume dial does nothing. The volume buttons on the steering wheel do nothing. The FM and AM buttons show not available screens and do nothing. The navigation sound does not talk. Bluetooth seems busted. The CD player does nothing. The AUX does not play or connect at all. There is absolutely no response from anything associated with audio on the headunit, but everything else on the headunit works fine like the navigation will work but not talk and the buttons (excluding audio related buttons) all work fine.

I checked the diagnostics and these can be seen below. I'm not sure what these really mean but I know they're almost all related to the headunit/radio system.

Also, it's a 2010 is250 and I replaced and checked the radio fuses and some others but couldn't find any amp related fuses. Regardless I don't think it is fuse or amp related.

Hello,

All those Codes shown in the last picture are related to USB and other Input devices, it could be that USB or AUX port got jammed or shorted, preventing the system from functioning. To test it, try taking the Center Console apart and disconnecting all Input Devices, like CD changer (if it is separate), USB and AUX ports and see if it will fix the issue. I've had to deal with issue in XV40 Camry where a Switch in AUX port that notified the system if the port is in use got snapped, preventing the AUX from coming on when I plug the jack in, so it can happen.

Hope this helps and best of luck!

Hi thanks for this suggestion. It is something different and I can do it before I replace the headunit or amp so its easier too. Ill give it a shot and lyk if it works
