If you bought a car recently, or even have one that's a few years old, it's possible that it might have some sweet new tech. However it doesn't have Android Auto, most likely. And if you use infotainment systems, you probably won't like the car makers infotainment system and would prefer Android Auto. There are ways to add Android Auto, for one, getting an after-market head unit installed in your car, like I did. But there are only a few options there. Pioneer have three head units to choose from and JVC Kenwood have just two. Additionally, they aren't cheap. If you don't know how to install the head unit yourself, you could be looking at, at least $700 for the head unit and installation. And that's if you wait for the prices to drop. to get my Pioneer AVH-4100NEX installed, it was over a grand.
One thing I've seen countless times on forums and even in our comments is in regards to using a tablet for a display in the car. We've seen countless videos of people who have rigged their Nexus 7 to their dashboard and have Android in their car. This would be great, and a developer has even done this by making an app for tablets that does Android Auto. However Google removed it from the Play Store. Obviously for safety reasons. But the least Google could do is give us more options. After all, that's what Android was built on.
Now, yes, Android Auto is still really, really new. And I'd expect to see some more head units available in the near future. But as for now. If you don't buy a new car that has Android Auto or can get the update to Android Auto when it's available, you're looking at a head unit that will cost you at least $700 when all is said and done. I'd also like to see some better head units. While the AVH-4100NEX isn't a bad head unit from Pioneer, the screen isn't that great compared to Hyundai and Volkswagen's built-in displays for their Android Auto units. Of course, the number one thing here for Google is safety, and that's completely understandable.
