Belkin has just sent its AirCast Auto adapter to the FCC, which is a device that brings Bluetooth connectivity to your car. The device features a 3.5mm audio cable that can be connected to your car’s stereo system, and once your phone is paired with the AirCast Auto, you can hit the button to answer calls or play music. The button will flash blue when incoming calls are detected, and features an adhesive backing for easy installation. If your in-car radio already features a 3.5mm audio input, this would be a simple and easy way to hook your phone up to your car’s audio system without having to fiddle with the vehicle’s internal wiring. Pricing or availability weren’t mentioned, but we’ll be keeping an eye on this.
