Start navigation on Android

Dear developers,

Can anyone help me to find the right tutorial/helpfull information? I seem to be lost in the vast amount of information here.

I have build a Android application (Build with Firemonkey).
From this app I would like to start the navigation to a certain address. Thats it, no more than that.

Thanks in advanve

It’s a little bit unclear whether you want to start a different application to perform this task, or you would like to implement navigation-like features inside your app (like here)?
