Toyota Alphard 2016 model here for an audio upgrade.
We installed the Pioneer SPH-DA160DAB and we used the Connects2 fitting kit to complete the installation. The fitting kit provides the fascia and a steering wheel interface which retains the volume controls on the steering wheel. Customer now has Apple CarPlay, Spotify, DAB, Bluetooth all at a touch of a button.
If you require something similar please get in touch.
