MMCS System Reset CDs

This Mitsubishi car navigation system (MMCS) was originally intended only for the Japanese market, with the on-screen language hard-coded to Japanese, GPS system calibrated to the northern hemisphere and only maps of Japan available on the system start CDs titled "Navigation Soft" that included part numbers such as MR285494-I / 0FEAFU-18 / SD1Y-254.

Some models of the system are made by different manufacturers and so different System CDs are needed depending on the hardware components of the system, e.g. by Sumitomo Electric. The system is an early example of the kind of GPS and multimedia functionality now built into most mid- to top-end cars. The MMCS system began appearing in some Mitsubishi models from the mid 1990's before being replaced with newer, more functional technology under the same MMCS name for Mitsubishi vehicles built from around 2003. The earlier version of the MMCS system is now no longer supported with official documentation and system 'boot up' CDs no longer available.

ITEX MMCS Products for Mitsubishi Vehicles

To answer the question of what our restart cd products offer, consider the example of a no-longer functioning Mitsubishi Multi Communication System screen as shown above - which only displays some Japanese text, but including in english, "CD".

This on screen message indicates that your system has lost its settings (which can happen after the battery runs flat or has been disconnected for example) and will need a "Navigation Soft" system reset CD to get the system working again. After using the reset CD, the Aircon, Radio, CD player, (plus Fuel Economy, Compass and Video functions where available) will return to normal operation.

Note: Unfortunately there are several limitations for the restart CDS;

• it is not possible to incorporate any country's GPS map data on the CDs

• the compass system cannot be recalibrated to the southern hemisphere

• the system time/timezone cannot be changed (it is controlled by the GPS satellite signals)

• the language cannot be changed (other than for the specific vehicle systems listed below).

However, included with the MMCS System reset CDs is a handy 30 page A5 sized PDF document covering the system's major functions as described below.

ITEX MMCS PDF User Guide Description

An informative and easy to understand 30 page A5-sized PDF overview of major MMCS features (e.g. Tape, CD, Aircon, Fuel Economy, Compass and audio/video quality settings) written in plain english, which will be sent via email. The manuals are more useful to be sent in this electronic format as they include links to other useful websites, high-quality 'zoomable' images and a built in text search facility and a clickable table of contents etc., also not using paper and inks is better for the environment.

The PDF manuals were updated to V3.1 in October 2016 to include reset CD troubleshooting steps, compass inaccuracy in southern hemisphere, TV converter advice for non-NTSC TV signal countries and instructions for connecting portable DVD players and other personal video players and other devices such as iPods, PSPs, and many models of smartphones - plus wiring diagram information for troubleshooting and modification such as enabling tv/video playback while driving.

Note: The PDF manuals do NOT include information about the touch screen version of the system used in some vehicles (which are designed quite differently), however the manual may still offer some general hints and advice. The PDF manual can also be purchased separately if no restart CD is required, see the following separate product page.
