A mid-summer update - as the lazy summer days continue.
The radio installation is partially done, with provision for back up camera and forward facing cameras.
First, the factory Cultus Diatone radio was removed. Mitsubishi supplied this radio, and since Japanese radio FM frequencies are incompatible with North America radio frequencies, a new radio was required. The factory radio was single DIN sized, with a DIN sized storage compartment directly below.

A spare Double DIN case was used so that a new Double DIN radio could be installed.

The original power and speaker connectors (shown on right) were retained and soldered/shrink wrapped to the new wiring harness that came with the Pioneer radio connector (on the left). The new radio has a parking brake input wire so that the DVD player can still play whenever it receives a ground signal to signify that the car is stopped with the parking brake engaged. It also has a Reversing (backup) camera input trigger wire so that the rear camera image will appear when the backup lights are powered. I am thinking of doing something different with this wire.
As the Cultus is RHD, and I will be driving on designed for LHD roads, connecting this trigger wire so that whenever the left turn signal is activated (primarily for safer major intersection left turns) may engage power to the forward facing camera (to be mounted in the left external mirror housing). However, the low position of the radio screen may be too hard to see while driving, and make it necessary to mount a second small monitor higher on the dashboard to display a forward image.

A universal Double DIN trim plate (not yet cut to size) was purchased for a few dollars to fill the gap between the radio and the center radio trim panel.

This is an inexpensive video input switch adapter, needed to support manual selection of front or rear camera views on the radio screen. I will be removing and relocating the A/B slide switch portion of this switch adapter to a more convenient location, such as one of the unused switch blanks located on the instrument panel)

The back of the Pioneer radio has a USB output jack and camera RCA video output jack.

Here, the new radio is powered up, and it displays the home page screen on its touch screen.

Here is a picture of this Cultus overhead map light. Normally, the interior light on a Swift or Metro has just a light and/or digital clock. I have not seen a NA car with these dual map lights before buying this car. It was sure handy while working on the wiring; the light beam was more focused on the center of the car interior.
