In-vehicle app testing is the next step for app developers who have already created a proof of concept using GM's next-generation infotainment software development kit (NGI SDK).

John McFarland, director of Global Digital Experience, said: "By introducing GM Dev Client, weâre giving developers the missing link they need to finalise their applications. It will help us and external developers make sure the best in-vehicle apps are ultimately made available in GM vehicles."

After building an application as proof of concept with the NGI SDK, the next development step is to conduct real-world testing using a GM vehicle's infotainment system. GM Dev Client allows partners and developers the ability to test their apps in a GM vehicle once theyve obtained approval from GM.

In January 2017, GM released the NGI SDK, which mimics real vehicle data and enables developers outside of GM to build apps without making frequent trips to Detroit to conduct testing on infotainment modules. With GM Dev Client, those apps now can be tested on a real GM vehicle anywhere in the US.

Kent Helfrich, GM executive director of Connected Ecosystem Integration, said: "Sharing more emulated data points through the SDK than any other automaker was the first step in opening the door for developers. After such strong adoption of the SDK, we wanted to enable developers to take the next step and allow real-world testing in our vehicles."

By the end of 2017, the NGI SDK will offer templated framework for developers such as a media player layout or a point of interest layout.
