Great suggestion! I fixed the problem and was able to eject cds. Thanks a lot!
My CD on my RX is a bog standard but it gives me these errors from time to time, had a few the last month or so when the car is cold, may be the discs are too cold or when the car warms quickly there may be condensation on the disc which will give a read error.
The first few times I had a real problem ejecting the discs until I came upon a simple solution.
Turn the unit off
Then turn off the engine so that no lights are on on the dash
Push down and hold the power button on the cd player, whilst holding it down, turn the key to power up the unit.
Remove your finger from the power button, you may need to press again to switch it on. Error should now clear.
This has never failed to clear the faults I have had ranging from unreadable discs to un-ejectable discs.
