What's the aim of our conversions? Easily read the menu systems and set everything properly, access menus just like:

  • Bluetooth Handsfree setup, including phonebook etc

  • Trip information/fuel economy etc

  • Vehicle service reminders

  • Display/Screen settings

  • Park Assist menus (if fitted)

  • Full use of HDD music functions, playlists

  • Menu Language option (for Lexus/Toyota only) also includes Spanish and French

  • Still works perfectly fine with a band expander for FM radio


Do we do navigation/maps?

No, why? It's simple. In order to avoid a lawsuit for copyright infringement, licensing each system is a must. But licensing cost per unit is too expensive, the maps are old and dated, support (further updates) has finished, and there is no more. What do we suggest? Use Google Maps separately on your phone, it's free, more intuitive, and constantly updated. Unbeatable really.

How do we do the conversion?


Lexus IS / GS:  Simple! A few tools and a little know how, and using an easy to follow video, remove the nav/audio unit, remove the Hard Disk Drive ( HDD ) from the back, carefully wrap the HDD up and send it to us with your vehicle make/model and year. We will apply the conversion update, and send it back to you to refit, easy!


Here are our handy online removal clips:

Lexus IS:
Lexus GS:

Lexus LS: Remove the entire screen unit and send it to us to reprogram. For the LS, we need to program the internal memory as well as the HDD.


Christchurch Local? For Lexus/Toyota units, we can do the entire job for you, drive in, drive out.

We can usually do this within a few of hours.

What DOESN’T it do?

Navigation/maps is not supplied, and will remain the existing Japanese maps on your system. However, after the conversion the annoying blue sea and map no longer show, and in most cases a compass will display instead.

All functions that are 'Japan use only' cannot and will not function outside of Japan. Please don't expect use of these functions. These include G Book, VICS traffic & weather, Operator services etc. TV is also disabled, and any TV function, which includes AV input (Aux Audio input is different).

(Note: using TV for Aux? there is another solution we can offer for standard Aux Audio input)


In the Japanese unit, there are 'Predictive Course Lines' that display on the reversing camera screen, and move with the steering wheel. Due to firmware constrictions, these camera lines will disappear, but the reverse camera image still works properly.

The factory Bluetooth system hardware Does Not support audio streaming, just phone handsfree operation, but the Auxiliary input is still functional for audio input.

Currently the clock (GS model and some LS models only) has missing text on the clock screen buttons, but you can still press them and easily adjust the time if required. It does not affect any other display/operations.


Will it change my speedo / instrument cluster?

No, the instrument cluster is a different unit entirely in it's own right, and as such no conversion of the entertainment system can change the instrument cluster/speedo, just the audio/navigation/ac unit.
