Answer to: Bose SoundDock Portable charging issueI purchased the BMR A2DP Bluetooth 4.1 Music Receiver Adapter for Bose SoundDock, iPhone from Amazon. That solves the problem of having your phone tethered to the aux cord. It also solves the need for a remote. Between the volume control on the sounddock and the volume control on the iPhone you can fine tune the volume from your phone as well as change playlists without a remote. You probably need to replace the battery. Try pcadaptershop.com that’s where I got mine.
