Mini MP3 Player

5610 MP3 player

I am trying to use
my 5610, which has a
built-in MP3 player in
my car via the car's
AUX input. I bought all
the right connections but
the car Aux input and
stereo do not recognize my
phone MP3. I tried it
on another car and the
same thing happened. I
tested using an inexpensive MP3
player and worked on both
cars so is not a
car problem



Any suggestions anyone?
