Is the original SoundDock Portable (2010) system no longer compatible with iPhone through the docking connection with lightning connection? I have an iPhone 7+
Thank you for posting and welcome to the community.
We cannot guarantee results using adapters for the SoundDock 10, but in theory, this should be able to still play through the system, but charging will not work.
I do encourage other community members to share their experience with the lightning adapters and our products for suggestions.
