CD ́s stuck

Hello dear R community, I’m looking for some tips on how to get my radio/CD changer to run again. Since my last camping holiday with the kids my drive is completely jammed. I think the three ??? audio games of my kids are to blame. I can neither eject CD-s nor new insert. the ad claims 3 places occupied and 4 free. Playing is also not possible. With each turn on the device tries to make a CD run for about 1 minute and then breaks My friend spoke of the fact that the whole center console has to be removed and the whole unit is then sent in. (about 3 weeks processing time). Costs if it is reparable approx. 1000 Euro or everything new for approx. 3000,-€. That I can no longer hear CD ́s is not so bad, but I can never make a Navi update again, moreover I fear that the harm a possible sales value significantly lowers. Would me over a few tips to look forward to. Thank you
