Xamarin ("old") Navigation side by side with Shell-Navigation

I am searching for hours and wondering if it is possible to use the old navigation and the shell navigation in one Xamarin APP.
Background:
The reason for that is, that I am maintaining an old app with 40+ sites - with different Navigation through the sites and sometimes complex data passing through them.
Try to achieve:
Now I've to implement some new sites and just wanted to put them into the Shell-Navigation. Those "Shell-Sites" should also be available in the "old navigation".
So yes - I could try to put it all to shell, but don`t have the resources yet AND: never touch a running system...

Yes, its possible.
First, understand that AppShell starts up by doing this in App.xaml.cs:
MainPage = new AppShell();
To reach individual pages from AppShell, see:
XF Shell Navigation / Register detail page routes.
To navigate away from AppShell into old-style navigation, do either:
Application.Current.MainPage = new SomePage();
OR
Application.Current.MainPage = new NavigationPage();,
depending on how your old navigation was done.
To return to AppShell, do:
Application.Current.MainPage = new AppShell();
To return to a specific page within AppShell, I'm not sure the exact details. Maybe after setting MainPage to appshell, execute a shell "Route".
CAVEAT: When you think through the above, you'll soon realize that you can't leave the old pages "completely" untouched. You need to decide what user will do to go "back and forth". Then decide how to only include that in the "AppShell" version of the code. But that is no longer an AppShell-related topic. Its a standard c# .net build question, plus making some UI decisions.

Adding waypoints to navigate in waze map

In my application i want implement waze map navigation for multiple destination,i just achieved single origin and destination navigation ,but here i want to navigation multiple waypoints.
String url = String.format("waze://?ll=" + Double.parseDouble(_Lat) + "," + Double.parseDouble(_Long) + "&navigate=yes");
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);

I'm looking for a solution to the exact same problem.
Looks like they don't wish to provide - clueless why they are afraid people would use that.
Anyway, would it be possible that the activity which opened the intent also has a simple GPS listener which calculates when you're (almost) reached (or passed) your waypoint, and set the next coordinates (in the opened intent / or new one) ...?
For now I'm using google maps with a full URL, still I wish to send my users straight into navigation, not a browserwindow that may have or may not have a navigation button (Chrome versus other browsers).
A simple A to B is not working for me, I need a "A B C, break, C B A".

How to customize root in android google map navigation?

I am implementing Google navigation by opening the URL -
https://maps.google.co.in/maps?saddr=xxxxxxxxxxxxxxxxxx&daddr=xxxxxxxxxxxxx

I have to set a new route from option at first and after that instead of default route, i want to show the route i selected first in my app...
please help me ..
thanks in advance

HERE Maps on Android freezes browser, breaking ajax requests on iOS

I am using HERE Maps to show a map letting users choose a location of interest. It works fine on desktop, but on mobile devices I am experiencing some problems.
On Android devices, if I create a map using
var map = new nokia.maps.map.Display(document.getElementById("map"), {
// Initial center and zoom level of the map
center: startCoordinate,
zoomLevel: 5,
components: [
new nokia.maps.map.component.Behavior(),
new nokia.maps.map.component.ZoomBar(),
new nokia.maps.map.component.ScaleBar()
]
}
);
the browser freezes after a few seconds. You can test this at karmap.com; try to scroll down to the very bottom to find the map. If I remove the code shown above the browser won't freeze anymore (but I won't get the map, of course).
Another problem occurs, when loading the page on iOS devices; in the form at the bottom you can find an input box named "Place of Birth". After typing 3 letters or more I start an ajax request to find suitable city names. This doesn't work if I use the following code (right under the code snippet to create the map):
map.removeComponent(map.getComponentById("zoom.MouseWheel"));
map.set("baseMapType", map.SATELLITE); // Activates satellite imagery on the display
If I comment that code out, the ajax calls work fine.
For me, that is some strange side effect! Does anyone have a clue what is going on?
Thanks for any help or advice!

Listener for new Button to get my location in GMaps v2

I think that it is a really noob question but i could not do it.
In new Google maps API for Android (v2) you can get you location right now touching the new button that appears on the map when you code:
myMap.setMyLocationEnabled(true);
That's works fine but I want to "catch" the event when the user touch this button because i want to add more actions and I don't know how to reference that button in code.
Anyone knows?
Thanks in advance.

GoogleMap.OnMyLocationButtonClickListener was just announced. probably going to be released today in the next Google APIs version.

This is not currently possible via the api.
A feature request is already pending and I think this will be added soon.
See this: http://code.google.com/p/gmaps-api-issues/issues/detail?id=4789

Oh yes, sorry. I should have read your question more clearly.
In order to your question:
In those situations, I recommened that you layout out your own my-location-button on the mapView and add a clicklistener on that and over location-listener, you can get the current position.
map.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(latitude, longitude), zoom));
