Mobile World Congress became an opportunity for car makers to meet would-be in-car infotainment app developers. GM used this fuel-efficient white Opel Insignia, not sold in the U.S., to lure developers to its site at developer.gm.com.
So far, 4,000 developers have signed up with GM, which claims that anyone with HTML and Java script skills can write an in-car app to present a car's functions or other apps on a car's dashboard display, or even to a passenger’s Google Glass, smartphone or smartwatch. GM's in-car OS is proprietary and based on QNX. GM said customers in China are eager to buy cars with in-car infotainment systems. Yes, you probably guessed, China is the world's largest car market.
