Navigation with DSP Amplifier

All navigation radios in these vehicles are in fact just simple screens with a tuner module located under the boot floor, next to the battery, and a navigation module behind the rear left quarter panel. To replace the factory navigation screen cables need to run from the aftermarket headunit to the rear of the vehicle.

The premium factory radio in this model was a navigation unit with separate DSP amplifier. This will be installed in the same rear left quarter panel as the other systems and can be identified by the 3 plugs connected to it. These amplifiers use a signal from the vehicles i-Bus data network meaning that removing the factory radio will stop them working and require bypassing.

Most of these vehicles use a quadlock connector behind the radio, however there are some with the older style round pin plug. The easiest way to confirm which is to remove the factory radio and physically check.
