For those of you out there with one of the Pioneer head units that have Android Auto, there is an update available. This includes the 4100NEX, 7100NEX and 8100NEX. The update will bring the head unit on up to version 1.05x, and is for those in the US and in Canada. The update is pretty simple, it improves voice guidance as well as fixing some bugs. This doesn't really affect Android Auto all that much, but it should help improve voice guidance in Android Auto. We'll have to test that out once we install the update on our own model. In addition to the Voice Guidance, the 7100NEX and 8100NEX are also getting AVICSYNC. What this does is it improves the built-in navigation and maps, which is provided by Nokia's HERE Maps (the built in navigation is really the only additionally feature these more expensive head units have).
You'll want to be sure you follow the instructions that appear on the display during the update. Because turning off the engine will kill power to the head unit and thus brick the head unit during the update. Something that no one wants to do, right? So it'll be a good idea to consult your owners manual before performing the update. The update should be available for everyone now, if not it'll be available in the next few days. If you use your head unit for things other than Android Auto, this is going to be a pretty important update. And even if you use it for Android Auto it's still a good idea to update.
Pioneer was first to market with Android Auto head units, and they were made available in three models. Since then JVC Kenwood have also brought in about 3 models that will give your car Android Auto. Pioneer's head units are pretty darn good, in fact, it's what we have been using for the past 8 months or so now, and would definitely recommend them. They don't send out updates too often (this is the first one for this model), so you won't need to perform an OTA all that often.
