i was given a logic3 Podium for my i pad 3rd generation. It fits nicely but somehow the sound and charging facilities are not working. The plug on the unit matches the socket on the i pad but it does not work. The only way I can use the stand is to connect the speakers via the headphone socket and selecting it for playback. It says that it is compatible with i pad 2. I would be grateful if anybody can tell me what can be done......that is, if anything can be done...! Thanks
