I have an FM transmitter in my car that plays a memory stick thru’ the radio. Unfortunately my new car didn’t come with USB input, although it has an ipod hook up, but the ipod wasn’t included.
Anyway, this little marvel (cost less than $8 postage included) will not play from the clip+ with or without the micro card. The player works fine when plugged into a wall charger, so the failure to play has to do with the audio signal connection which is absent in the wall charger. Needless to say, the FM transmitter works fine with a memory stick.
