my unit freezes after a while when playing music from sd card or usb flash drive

 

when i unplug the sd card or usb flash drive, everything goes back to normal

 

i have a 8gb sd card

 

i read about a fix somewhere here but it was very unclear

 

i have a lot of music organized in different folders

 

please help/ i am tired of switching CDs to CDs all the time so i can use my sd card or usb flash drive

 

can someone who had this issue before , tell me step by step how to fix this freezing problem ?

 

thank you in advance
