    well after a lot of link testing I have solved it for me:

    <a href="http://maps.google.com/maps?q=loc: <lat>,<lng>&navigate=yes">nav</a>

    this one is opening the user nav app choosing menu, and it pass the cords you wish to navigate to.

    enjoy

    Since this question was first posted and answered, as of Oct. 2017, Google has developed an API called Maps URL.

    It is a universal, cross-platform URL for launching google maps.

    https://www.google.com/maps/dir/?api=1 is the endpoint for maps that could include navigation.

    You add the following parameters:

    • Origin: &origin=new+york
    • Destination: &destination=san+fransisco
    • Navigation: &dir_action=navigate

    If you leave out the origin, it will detect the location of the device, which is probably better for navigation anyway:

    https://www.google.com/maps/dir/?api=1&destination=san+fransisco&dir_action=navigate

    This will not immediately open navigation, but will take you to a google map, which will have the navigation icon on the page, and will give the user the option to use the app (or download it if they don't have it). This seems like a good solution. I just tested it in my browser, my Google Pixel, and my iPhone and it works the same on each mobile device.

    Check out the rest of the documentation for more useful features: https://developers.google.com/maps/documentation/urls/guide

    You can use geo links to open the navigation app on Android. Unfortunately this is not supported under iOS. But generally you have to remember that you can't directly control how this link is handled on the device, as I said iOS does nothing or may even show an invalid link error, and there may be Android devices which also do not support this feature. Just remember that you cannot be sure if it works anywhere and as such your website should not depend on this feature, it should just be an extra bit of usability for devices which support this feature.

    1) Showing a location in a native map app

    With the geo link you can specify a location like this:

    geo:longitude,laditude

    Or like this:

    geo:street+address

    You can also search for an address like this:

    geo:?q=street+address

    You can also define a zoom level like this:

    geo:street+address?z=3

    And it is also possible to combine multiple parameters like this:

    geo:?q=street+address&z=15

    But beware that this does not work as expected. In this case in Google Maps it starts out with the defined zoom level and then starts the search an zooms in on the target.

    Here is a little bit of Android documentation.

    2) Opening a route in Google Maps

    You can also use the following link to just show a route between two locations:

    http://maps.google.com/maps?saddr=street+adress&daddr=street+address

    And coordinates also work with this:

    http://maps.google.com/maps?saddr=50,10&daddr=50,20

    You can again use it like this:

    <a href="http://maps.google.com/maps?saddr=New+York&daddr=San+Francisco">Route New York --> San Francisco</a>

    3) Immediately starting a navigation

    With this option the link opens a route to a location and the device doesn't just show the route but it immediately starts navigating:

    google.navigation:q=street+address

    You can also use coordinates:

    google.navigation:q=50,10

    You would use it like this:

    <a href="google.navigation:q=San+Francisco">Navigation to San Francisco</a>

    4) Testing

    I have tested everything on a Nexus 5 running Android 4.4 (KitKat) with the following HTML:

    <!DOCTYPE html>
<html>

<head>
  <title>Geo Link Test</title>
</head>

<body>
  <p><a href="geo:50,10">Location 50/10</a></p>
  <p><a href="geo:Vienna">Location Vienna</a></p>
  <p><a href="geo:?z=5&q=New+York">Zoom 5, Search for New York</a></p>
  <p><a href="geo:?q=San+Francisco&z=15">Zoom 15, Search for San Francisco</a></p>
  <p><a href="google.navigation:q=San+Francisco">Navigation to San Francisco</a></p>
  <p><a href="google.navigation:q=50,10">Navigation to 50/10</a></p>
  <p><a href="http://maps.google.com/maps?saddr=New+York&daddr=San+Francisco">Route New York --> San Francisco</a></p>
  <p><a href="http://maps.google.com/maps?saddr=50,10&daddr=50,20">Route 50/10 --> 50/20</a></p>
</body>

</html>
