The display audio is being expanded to modern new models, regardless of domestic or imported vehicles.
It is very convenient to use this as a car navigation system, but it is very convenient to use this as a car navigation system, but it is very convenient to use this as a car navigation system.It was a problem with operability (operations other than driving in the first place would be illegal), and the hurdles were high for using navigation applications on smartphones and tablets.
However, this "display audio" solved the problem.The connection between familiar smartphones and cars has greatly improved operability problems.

Eliminate car navigation functions and substitute for smartphone apps
Display audio is often translated as "DA", but simply puts the navigation function from existing AV -integrated car navigation, and instead, it is an in -vehicle device that replaces the popular "smartphone navigation" app.be.
In North America and Europe, DA, which uses the "mirroring function" that displays smartphone screens as it is, has always existed, and products that are close to this have been sold in Japan.
Toyota has boarded to expand the market at once.
The new Corolla announced on September 17, 2019 is standard equipment.
It is new to remember that we have cut off a good start dash, such as working with the corresponding smartphone app (partially paid) to support not only car navigation systems, but also for subscription (flat -rate) music apps.
In particular, Toyota will later find out that he is serious about this DA.
It was easy to predict the standard equipment because the sales volume was expected to be installed in the Corolla, which was synonymous with the popular car, but it was at best that the recruitment itself would be a "C segment" model.。
However, it is clear from the fact that the reality was partially improved to the C-HR and the upper class Camry.
What are the actual advantages and disadvantages?
Specifically, the advantages and disadvantages of DA are as follows.
■メリット
（1）ディスプレイ自体は付いているので、対応するスマホ＆アプリがあればすぐに使える
(2) The cost of the early introduction is reduced regardless of the manufacturer option, dealer options, and commercial sales
(3) Since the smartphone itself is a "communication equipment", the latest telematics environment can be easily built.
(4) Map updates and functions are basically performed on the navigation app, so the speed of updates and evolution is overwhelmingly fast.
(5) You can choose the app according to your preference
■デメリット
（1）使用頻度にもよるが基本ナビなどのアプリを使う際の通信費（パケット代）は自分持ち
(2) The position accuracy of the navigation is left to the smartphone.In other words, the performance of the GPS and sensors also has a difference in the ability of the smartphone.The most prominent thing is the GPS radio wave in the tunnel, so the position display is often stopped.
(3) Although not all, there are many cases where CD / DVD players have not been implemented so far to eliminate unnecessary functions and realize cost reduction, and there are many customers who are disappointed at the dealer (to complain.No)
(4) UI (user interface), in other words, it is still not a dedicated machine in terms of ease of use.
(5) The connected smartphone itself is vulnerable to heat, so it is necessary to keep it in a place that is not affected.
There are some differences in individuals, but this is generally like this.
As mentioned above, the advantage of DA is highly reduced in cost at the time of initial introduction, but car navigation system is not required in the first place!In some cases, for those who can be considered a wasted equipment.
Also, as I wrote in the disadvantage (1), if you choose a paid navigation app itself, a monthly fee will be incurred.
All you have to do is choose a free app, but the paid apps have excellent functions and performance.Navitime Japan's "car navigation time" is a good example.
