CD changer

[DeFran50]

hey everyone..just want to see if anyone else has ever had this problem?..I have an 03 4.6 with nav and a 6 disc cd changer in rear..all of a sudden the last few weeks or so..when i go to play a cd it reads NO DISCS...and I dont understand it...I was just playing cds fine not to long ago...so I ejected my magazine and put back in..nothing..I have taken the cds out and made sure all were label up..which they were.. I took all 6 cds out and put them back in, in different slots...then put magazine back in and still nothing...I dont know what to do..any help would be great..thanks
