Panasonic CQ-C5110U Playback Issue

HIYA..! i have a panasonic cq-c5110u installed in my vehicle... the problem i face with this unit is this that it stops playing after exactly 10 minutes. I mean, it starts perfectly, plays well but after 10minutes, the volume drops to 11 from 20 and then "SEE YOU" appears on the head unit. I have to de-attach the head unit and attach it back and again it starts and goes for 10 minutes and it goes on and on and on like this.. I am worried about the pins fo the falp by frequently attaching and de-attaching it.. CAN ANYONE PLEASE PLEASE PLEASE PLEASE HELP ME OUT..! people say its a security issue and that there must be a code for it..! i dont know.,.. but please, help me out.. its taking the fun out of listening continous playback..!
