Jammed Cd Changer For 2008 Sienna Limited Awd With Navigation System.

I have a 2008 Sienna Limited with Navigation set up and my CD changer has jammed and I can't eject any of 4 CDs that are in the changer (it has 4 positions available on the screen). The CD in position 3 will play but none of the others will play. It attempts to change and eventually shows CD Error. The CDs are home made mp3 disc. There has been a slow response to loading and ejecting the CD's since I purchased the vehicle just over 6 months ago. I went to a Toyota dealer already and they were unable to remove the CDs or give me any recommendations, aside to taking to a car stereo service. I read a few sites that recommended to remove the power cables to reset the player or remove the fuses to the player for 10 min to reset, or disconnect the car battery. Any recommendations?
