These apps only support limited functions of Map, Music and Phone. On the other hand, G-Link app for Android phones and iPhones to use G-Link, ELVES Automotive developed smart phone connectivity, enables users to add any apps in their smart phones, video view restriction while moving, and both-way touch control.
