You can get it out.
That happened to mine and I just pushed theejct button over and over again. eventually it came out. I never use cdsany more. With the 430n you have a hard rive and you can down load music form a playlist on cd or from a flash drive directly to the hard drive, put all your "forever music" on that I have loaded about 2000 songs on it because the radio is well it S----! The auxiliary in put requires a stand headphone connector. Use this all the time too. I down load audio books form audible and plug the phone into the auxiliary jack and list to books . But wait in my shopping for a new jeep was desperate to find one with a 430n again and I stumbled on to the Insane Audio JK2001 radio . This has a hard drive like the 430n but with 250 gigs of memory, built in nav, built in topo maps, built in monitoring program for your motor I think it is callTorque or something but it monitors rpm temp oil temp coolant temp etc. It runs on an android platform and you can add memory via an sd card. doit millrun any android app you have. including t stuff like US topo maps back country explorer google nav and all kinds of stuff. IT cost just about the same as ordering a 430 n on anew jeep. but is way way more powerful . It connects seamlessly with all of the steering wheel controls. It is water proof dust proof shock proof and American made. That is my plan. It is specifically made for the JK. Hope that helps.
