Almost every modern hands free car kit is equipped with connector to integrate it with vehicle’s audio system. Providing correct installation, calls are directed to audio speakers, and appropriately mounted microphone enables voice transmission with minimal losses caused by the surroundings or vehicle in motion.
Hands free kits designed for permanent installation (Nokia, Bury, Parrot) are usually equipped with ISO connectors (for power supply and speakers). However, the majority of new cars do not feature the ISO connectors anymore, as they are replaced by new ones compatible with the latest radios and car installations (ISO2, Fakra, Quadlock, etc.).
This compatibility problem can be solved by using the HF-xxxxx connectors. They allow you to connect any GSM set to your car’s system, and benefit from all of its features.
Knowing your car’s make and model, you can choose an appropriate HF-xxxxx connector from the catalogue. Some of them are designed for groups of vehicles, so each connector is accompanied by a list of compatible cars.
