1. These instructions apply to R.1.5.1.4 or later revisions. The revision info can be found on a small white sticker on the interface and
packaging.
2. The radio select rotary switch, on the side of the interface, must be adjusted to the proper radio setting before plugging the interface into the
vehicle (see next page for setting chart).
3. The interface comes pre-programmed for all of the vehicles factory SWC functions and does not require programming, unless you wish
to re-assign the SWC functions, or utilize short press long press dual command functionality. The SWC can always be restored to default
settings by pressing and releasing the program button on the side of the interface once, and waiting 7 seconds for the LED to ash 4 times.
4. Vehicles equipped with factory navigation must follow the installation tech brief listed at www.pac-audio.com under the RP4-HD11 product
page.
5. Vehicles equipped with a 7” touchscreen: Once the factory head unit has been removed, you will no longer be able to set the clock
or date on the factory display, as this is derived from the factory head unit. The date on the screen can be permanently removed by
disconnecting the batttery to clear the screen’s memory. In order to set the clock you will need to disconnect the vehicles battery at 1:00, as
this is the time the screen defaults to once it has been reset.
6. The LED will ash whenever a SWC button is pressed.

The RP4-HD11 interface allows the replacement of a factory radio in select Honda vehicles with MSCAN databus radios. Using this
interface will retain factory features, such as steering wheel controls (SWC), the factory amplier, and the ability to set the factory
clock when the original radio is removed. Use of this interface also allows you to program two radio functions to each SWC button by
using short press long, press dual command functionality. The RP4-HD11 also provides data bus driven outputs, such as accessory
power, vehicle speed sensor (VSS), illumination, reverse trigger, and parking brake.
