Fidelio 7500 after 6 months of owning plays music but will not charge i-phone or i-pod 4. Return through warranty. Receive replacement only to find error message when docking that states "Charging for this accessory is not supported". Call Philips only to hear "please update your i-products to the latest version 6.1. Clear all music and many apps off one of the products, wait two hours for download only to find same message: "Charging for this accessory not supported". Why oh why did it work for 6 months and not now? Feeling really ripped off since charging of my two units was always an issue but the sweet sound made using this item a win, win.
