This is cross-platform it is URL based.

of course, you can put "origin" another Postcode or city, address etc the same for the destination.

Sub LoadMap
private Postcode as string ="CM20 3PX"   ' <--- an example
Activity.LoadLayout("loadmap")      
            WebView1.LoadUrl("https://www.google.com/maps/dir/?api=1&origin=current+location/&destination="&Postcode&"&dir_action=navigate")
End sub
