i bought a in dash 7"lcd dvd player or known as ma7dvd from a friend for 350 bucks..... got home to realize that the back has NO sound outputs what so ever!! the more i looked into the player the more i noticed that the only audio out that it has is a FIBER OPTIC digital out. WTF?? any one have one of these?? am i missing a piece or somthing? would really like to hook this up but have no damn clue...along with any supposed sound shop in the area. There all worthless. any help would be great.
