Had the alternator and battery replaced and now the radio does not work. I see from other sites that a reset code may be required. Does anyone have it for a 2007 GX470?
Update. The Toyota tech did not check the fuse! I checked and it had blown. Wow, what service! New fuse and radio works again. That said the windows had to be reset as one would not work from the driver's control. Disconnecting the battery does seem to have some associated problems.
