I have a 3g 15gig iPod and its been doing so well. Nothings ever been wrong with it. I bought the naviPro ex and the lady at the store said it should work for mine. I bought it. And only the play/pause, fast forward/back, and rewind/next work and the volume. all the other buttons dont not even the repeat and shuffle buttons. Does anyone else have this problem? Am i doing it wrong? Should i take it back (cause the lady said if it doesnt work i can take it back).
