Options for connecting external audio and/or video

The Toyota ‘factory’ option

The Toyota option for external input consists of sockets located in the centre armrest.

After-market alternatives

An aftermarket modification to the audio system included conversion of the radio to English labels as well as the provision for external input.

DIY alternatives

Since the TV tuner is not compatible with Australian standards, the wiring from the TV tuner to the EMV can be repurposed so as to provide external audio and/or video input.

Basic concept

Simply disconnect the TV tuner and then hook into the relevant wires:

  • The TV tuner is located under the rear seat on the drivers side.
  • To listen to the new Audio source, select the ‘TV’ input of the EMV.

This can also display video (in NTSC format) while stationary. If video is desired while underway (eg for an external GPS navigation system), a further modification is needed.

Example implementation

To provide for a plug-and-play solution, a connector from a spare Tv tuner can be used to connect a Bluetooth stereo, which is then used for music, navigation instructions, and phone calls.

  • de-solder the socket from the tuner (a heat gun makes light work of this task)
  • solder power, ground, audio and video cables to it with standard connectors of your choice
  • plug in eg your new Bluetooth stereo
  • mount the stereo in your location of choice. Eg.
    • somewhere visible and easily accessible, or
    • in a hidden ‘stealth’ location, eg in the glove box or under the seat
  • pair your mobile phone to the Bluetooth stereo
  • use eg Siri (iPhone voice assistant) to control eg Spotify music, phone calls, text messaging etc etc

Advanced options

Steering wheel control can be implemented by modifying the (optional) Telephone controls and then connecting this to the stereo’s remote-control input.

Alternatively, some sort of Bluetooth button/keyboard could potentially be paired to the stereo.
