CarPlay USB SI Consulting

Developers must complete certifications required by the Apple MFi Program before going for mass production. As an independent test lab, Allion is authorized by the USB-IF to test USB technologies, including USB signal integrity, which is one of the mandatory CarPlay test items. We can add value to your business by providing product development consultancy, signal integrity fixtures, test environment setup, and post product launch analysis.


What is CarPlay?

In 2014, Apple first introduced CarPlay as an in-car platform which includes navigation, music streaming, hands-free calling, text messaging, and many other features. Users can connect their iPhones to the head unit via wired connections (USB) or wireless network (Bluetooth, Wi-Fi). They can also control the built-in display by using the touchscreen, turning control knobs, or giving voice commands to Siri. As the in-vehicle infotainment system gets increasingly popular, more and more iPhone users consider the presence of CarPlay when car-shopping.

Certification Process Flowchart

Test Items

Some of the CarPlay test items are highly complex, for example, USB signal integrity, USB performance, and ITU-T Telephony Audio Quality. Particularly, vendors have to acquire USB-IF TID to submit the USB signal integrity test results to Apple.

At Allion, we offer more than just CarPlay consulting services. As an independent test lab, Allion is authorized by the USB-IF to test USB technologies. We can add value to your business by delivering a comprehensive suite of tests and accelerating test schedules.
