Navigation Computer Module - ASIA: Notes

In some Asian markets the vehicle is delivered with UK line item, or an after market navigation system is fitted at PDI (pre-delivery inspection) by the dealer or at Port of Entry (POE). A medium speed CAN based navigation computer module is fitted below the front left seat.

The navigation computer module outputs the video signals in a LVDS format direct to the TS. Audio output is passed to the IAM which converts the signals and passes them to the audio amplifier on the MOST ring. When Audio is required, such as a Voice guidance instruction, the Asia navigation computer module communicates to the vehicle audio system using a hard wire connection between the TS and the Asia navigation computer module. TS co-ordinates and vehicle power mode status are obtained through the medium speed CAN. Map data is stored via a multimedia Secure Digital (SD) card accessible through an access point on the module.
