Radio failure
My 2003 Lexus GX 470 radio will not turn off, its display is dark, the cd player will not eject and the radio channels do not change. The only way to turn down the sound is on the wheel. Can anyone help with a solution to this situation? Thanks

I want you to go and check the codes via the Diagnostic Mode. Do the following. Since you do not have NAV.
1. On the radio while pressing the "Disc" button 3 times, Press and Hold Presets "1" & "6"
If you happen to get P440 ( NCON ( No Connection) that means you antenna Amp is not powered.
Remove the Receiver Assy and check the Harness assy continuity. Normally this the culprit.
