plugging into car stereo aux port and only getting sound on one side of the car

I just bought a clip zip.  when I plug it into my the 3.5mm aux cord on my car stereo there is only music on the right front and rear speakers, not the left.  I have not had an issue before when plugging things in.  thoughts?

If it play stereo using earphones and other devices play car radio in stereo, then it has to be a cable problem, Make sure cable is pushed firmly in at both ends.

Make sure u hear a ‘‘Click’’ sound when u insert the car stereo aux jack into ur player.
