No dealer appointment. No installation costs. No SIM card hassle.
The HWA1 Wireless Interface brings the original PCM for Porsche up to date – in under 30 minutes, without touching a single screw on the car.
Old-school soul. Modern connection.
You didn't buy your 996 to spoil it with a phone mount on the air vent. The HWA brings hands-free calling and music streaming into the original PCM: invisible behind the unit, and removable at any time.
