Secret of Google Maps silent navigation

The year before, Google added many interesting features for Google Maps, such as GPS navigation. Although Google Maps in China is still relatively simple, the map of Google map in the United States can compete with professional map companies. More importantly, the cost of using Google maps is low. With the application model and promising prospects of another Google product Google Earth, Google Maps naturally becomes a heart disease for GPS professional manufacturers such as Garmin and tomtom.

However, Google map has not yet provided the voice navigation function. Although the software will display a magnified window before turning, it is not a good habit to watch the GPS Mobile Phone screen while driving. Therefore, more people think that Google map is more suitable for hiking.

There are a lot of speculation in the industry about why Google map does not provide voice functions. For example, Google map does not offer it intentionally to prepare a fully commercial version. This version is only a demo; google maps is only one of its exploratory products, most of which will be abandoned halfway. Google had to launch the castrated Google Maps version due to the pressure of map authorizer.

However, I have seen some reports. Maybe Google maps is the current situation because Google just wants to push a platform and provide some basic materials, such as road network and key reference point coordinates. More things may wait for Google to open the development interface and hand it over to third-party manufacturers or developers to develop more applications, such as voice navigation and more poi. Open Platform: This is Google's style. Google only needs to grasp the core.
