I have a 2016 VW Sportswagen that I use with my iPhone all the time. Everything just works and in 10 the Maps app in Carplay has gotten better.
About a month ago I was driving with a friend of mine in the passenger seat. Driving 45 minutes to some trails upstate. I asked him to put his Maps on (Android) so I don't need to get my phone out of my bad and fuck around with it while driving. He's got Galaxy 6 edge+ so I figured it just work... Boy was I wrong.
When he plugged it in nothing happened except autoplaying some music. Since I'm driving how no idea how to make it work. Turns out you need to download an App from the app store to make it work... but Android gives you no notification about it.
Then there's a whole on-boarding process you got to click through. Then you need to agree to let the Android connect to the Car all in all about 5 different agree prompts. Took about 30 minutes to get this going.
After all that the car would lose Android Auto connection with the phone every few minutes. Apparently it's a know issue with that model of Android and VW.
What a terrible experience. For a while I was thinking of getting an Android phone next time I need a new phone (break, slow/sluggish). Not going to happen now.
