Remedy
Purchase the HDMI to Lightning adapter
directly from Apple. Not all 3rd party
adapters work the same.
Do not plug into the USB from the Alpine
head unit. A third party USB adapter will
need to be used that is 2A.
If the phone has the feature to use an HDMI
adapter it must be the one purchased from
the manufacturer of the phone, not a third
party adapter.
Do not plug into the USB from the Alpine
head unit. A third party USB adapter will
need to be used that is 2A.
Plug the adapter into another monitor (for
example a television in the home) and reduce
the resolution settings.
In the i407-WRA settings confirm the serial
number. HOME/SETTINGS/GENERAL/

as shown on page 14.

Every harness needs to be plugged into it's
proper place. Follow pages 14 and 15 and
ensure every connection is going exactly

VIDEO IN/OUT port accidentally.
Test the power wires with a digital multimeter
and trace from there.
Check for proper connection or
disconnected pins.
