Occasionally the Parrot Car Kits need different connectors to the ones on your stereo. Provided that your head unit is not amplified, we can supply an adaptor to suit most of the current vehicles on the market (N.B May not suit some Sat Nav systems). The SOT range of leads are designed to plug onto the end of your Parrot phone harness and turn it from ISO to the vehicle specific type connector you require. There is no need to worry about connecting a mute wire as all the muting is done by the Parrot loom relay box.
