It has happened three times that discs with new tags on them are sticking in the car radio. I have shut off the car let it get cold and then turn the car back on and it pops out.
We are sorry for your frustration with CDs that have our new RFID tags on them. Prior to adopting this product we did quite a bit of testing with car CD players, home players, and mobile players, and had no problems with discs sticking. We have heard of this happening only a couple times at other sites around the country that use these RFID tags. So it's certainly unexpected. It's good to hear that you are eventually able to eject the discs, albeit as a workaround.
