Well i own a 16 trax lt i believe all you have to do is pair it using bluetooth as far as the icons i am not sure because android auto is not installed on all of the 16 trax. The best place is to do a search on youtube or someone on here will clue you in.
I have a 16 Trax LT, so I know that pairing it with Bluetooth is all that's required. However, I'm not sure about the icons since not all 16 tracks have the Infotainment System enabled. The best place to look is on Google, or someone on this site may direct you there.
