I have a DCB352 which I was bought for Xmas, I have only used it for the radio until today and have now tried using it as a dock for my IPad, it plays the music at first but then the charging of the IPad keeps starting and stopping, very briefly but each time it does it then bleeps, also I get a message keep coming up on the IPad saying Apple does not support this accessory, finally every so often the currently playing track will just stop playing half way through, sometimes it will stop during first track other times it might play several and then stop, obviously this all means it is totally unacceptable, have I got a duff unit which I need to return to the store it was purchased from for exchange or are the claims of compatibility untrue
