Bought for IPod IPod 4. displays the connection "Charging is not supported with this accessory" to a docking station, it's very hard ... In addition, this plant all the apps and Associated disconnects bluetooth speakers. Well, the seller first offered me 3 after application for return ??? !!! then finally repaid me when I insisted ... leaving me all and advising me to give it to a friend who surely appreciate the gift !!! Must be of humor 3rd degree ... Otherwise, no product, to be avoided
