Car Multi-function Screen Stuck "checking Usb Device.. Wait"

[dee27]

Can somebody please help me ...

Today my car screen (for no apparent reason) is stuck with the message "Checking Usb Device.. Wait". Please see attachment.

I have unsuccessfully tried absolutey everything to clear the message or even move to another mode i.e. radio. I have tried to turn the engine off and then back on, remove the USB and restart engine (etc) but nothing seems to work.

Has anybody experienced this problem or does anybody have a solution? Thanks in advance, Dee.

You should be able to reset the system by pressing and holding the stereo power button for a few seconds until it reboots.

Thanks for the reply Colin but I tried that as well.

As I have had no other suggestions I guess this a software problem unique to my car.

It does seem you have been unlucky with this one, I've not heard of anybody reporting this before.

The only thing I can suggest is a full reboot by disconnecting the power source. Typically there is a fuse marked RADIO on Lexus vehicles within the cabin fusebox, but I'm not certain on the CT. Either pull the fuse or disconnect the 12v Battery for 1 minute and reconnect. If you disconnect the Battery then the alarm may go off when you reconnect it so be ready to press the unlock button and/or turn on the ignition.

Otherwise you may have to take a trip to your dealer.

Looking in the owners manual there appear to be two fuses which are probably worth pulling. Only one would be necessary but I don't have access to the wiring diagrams to confirm which one - easier just to remove both for 60 seconds:

RAD No.1 15Amp in the engine bay

RAD No.2 7.5Amp in the cabin
