OK so after hours of pouring over the wiring / system diagrams for the car, iv determined that it is only possible to install the sat nav unit in the lower end cars (replacing the base audio / radio unit) provided: 1) you purchase a brand new sat nav unit that has never been locked to a previous car...

im 50% thinking to give up! iv read that 1 or 2 people have done this before and one guy was selling a converter cable he made!

WARNING! If anyone is about to do this! do not plug in the navigation unit in the car with 20pin and 32 pin connector. 1 of the pins on the 20pin connector that fits in, is incompatible with the sat nav unit, both 20pin and 32 pins connectors will need an adaptor between them and the nav unit.

Here is my current plan for the wiring adaptor im going to build. iv managed to source the connectors from China. Blue highlights are what im going to connect together, and the orange ones I may also connect but want to do a bit more investigation first to make sure its safe. https://files.gitter.im...

I have tables that tell you what the numbers are, so I can make an adaptor. In case anyone else is looking for information! Do not match the numbers, you could damage your car, if I succeed in making a working adaptor I will post the diagrams and information on how to build it.

I think iv found in service manual connectors for the old audio unit (as photographed in original post)



And also the connectors for the full satnav



Investigating how to make a connector.

Im finding parts like this on ebay, but no idea how to identify the correct wiring loom that connects steering to head unit!

Thanks, seems the clue is that I need to replace cable from steering wheel to the head unit, hence the wrong connector (or possibly work out how to make an adaptor) Does anyone know where I can get the steering wheel cable? Or find a pinout / wiring diagram or the cable in my version, and the one fo...

Hi, Im trying to replace the standard radio with the full satnav unit, iv got it connected and half working. However the secondard connector that goes to the head unit its a different size and has 32 pins. Iv read that it is possible to get it to connect with an adaptor and someone was selling them ...

Hi, did you ever solve this? I have also the same issue.
