I have an older Bose SoundDock Series 2 (serial #04937 191342 2929AE) and need a new iPod. Looking @ the 32GB iPod Touch 6th gen. I contacted Bose per compatibility/lightning connector and was advised to buy the CABLE adapter instead of plug. Contacted Apple and was advised to buy ' lightening to 30-pin adapter'. The photo of this shows a plug.Would like to know exactly what I need. Any help greatly appreciated.
