If you are installing the Hard Disk based comand in an older car without an existing phone system then you need to add a microphone. This microphone has all the correct connector to make this a simple task.

Also suitable for NTG2.5 Audio-50-APS and Audio-20 with built in bluetooth.

If your car already has a phone system, then you need the adapter loom that we sell seperately.

You will also need a bluetooth antenna and an FM antenna adapter and a GPS antenna.
