Q：

1.I am navigating and when there is a phone call, it jumps to the bluetooth interface to talk, how can I make a call from the navigation interface?

2.How can I realize that I can hear Android's navigation voice prompts even when listening to the radio in the stock interface?

A：Need to select path for navigation in setings.

Routes: Setting->Navigation-> Select Navi APP you want.

（Note: KOASON Mercedes-Benz, BMW, and Audi Android screens only have different UIs, but the setup routes are the same.）

2.Click the navigation icon on the Android main interface to enter the navigation.

Note:

1. When you use Carplay navigation or Android Auto navigation, there is voice prompt only when you are in the navigation interface, and there is no voice prompt when you switch to the original car interface.
2. When using Carplay or Android Auto navigation, when there is an incoming call, it will be switched to the call interface, and you can't make a call in the navigation interface.
