One of the biggest issues when using any navigational software, including Google Maps, in a car is tunnels as they are known to affect navigational accuracy. However, it seems that Google has found a way to solve this problem, at least on the best Android phones.
There is little doubt that Google Maps is one of the best navigational apps on the market. The program is easy to use and works seamlessly with Android Auto. It appears that Google wants to improve on this even more with the inclusion of Bluetooth beacons to aid with tunnel navigation, as reported by SmartDroid.
