====== Navigation Settings ======

===== Router =====

Locus Map does not contain its own service for calculating routes. Therefore, **[[manual:user_guide:tracks:planning|Route planner]]** and **[[manual:user_guide:functions:navigation:point-to-point|Navigate to]]** features cooperate with **third party routers**. Each router has specific properties, some is functional online-only, some works offline (after downloading offline navigation data):
{{ :manual:user_guide:functions:navigation:naviset01.png?nolink |}}
==== ONLINE ====
  * **[[https://www.graphhopper.com/|GraphHopper]]** - very fast and data-efficient routing service. Suitable for all ordinary outdoor activities - three kinds of bike profiles: **cycle**, **MTB** and **racing** and two types of walk profiles: **walk** and **hike**. GraphHopper offers also a **car** navigation profile with sub-settings - avoiding highways, tolls, and ferries.
  * **[[http://wiki.openstreetmap.org/wiki/YOURS|YOURS]]**- open source routing engine offers point-to-point route calculation suitable for guidance without voice commands. It has very good results in calculating **bike routes** (fast/short) but can be used also in a car (fast/short routes too).
<WRAP round info>Interesting comparison of OpenStreetMap online routing engines can be found [[http://wiki.openstreetmap.org/wiki/Routing/online_routers|here >>]] </WRAP>
==== OFFLINE ====

  * **[[https://play.google.com/store/apps/details?id=btools.routingapp|BRouter]]** - external offline router - requires the installation of an independent application **BRouter** and downloading offline navigation data:
    * launch BRouter\\ \\ {{ :manual:faq:navigation_offline01.png?nolink |}}
    * select Download manager\\ \\ {{ :manual:faq:navigation_offline02.png?nolink |}}
    * zoom in and select the area you need for offline routing\\ \\ {{ :manual:faq:navigation_offline03.png?nolink |}}
    * Confirm downloading of the selected data file.

BRouter offers many more routing profiles with additional configuration:

You can also change the profile selection:

=== Advanced settings ===
{{ :manual:user_guide:functions:navigation:navigace19.png?nolink |}}
With these, you can link external profiles to the in-app selection:
  * tap an in-app profile and select the corresponding external profile from the roll-out selection:\\ {{ :manual:user_guide:functions:navigation:navigace20.gif?nolink |}}
  * rename the in-app profile, if necessary
<WRAP center round tip>
**External profiles** - besides the BRouter profiles embedded directly in Locus, it is also possible to use profiles provided by BRouter developer or by other users. **[[https://github.com/poutnikl/Brouter-profiles/wiki|Poutnik's GitHub page]]** provides further information as well as many ready-to-use profiles which should be downloaded and placed in the directory **/Locus/router/profiles2**.
</WRAP>
 
  * **GraphHopper**  - BETA version of an offline version of the routing engine. This option is displayed when a special add-on is installed. More information [[http://forum.locusmap.eu/index.php?topic=4036.0|here >>]]
===== Link with presets =====
Linking with the app **[[manual:user_guide:settings:presets|presets]]** enables **fast re-setting of the whole app after the navigation start** so that its preferences are **better suitable for navigation**. E.g. cursor is shifted, map rotation is on, the screen is turned permanently on etc. Three most used navigation profiles can be linked - walking, biking and motor vehicle:\\ {{ :manual:user_guide:functions:navigation:naviset04.gif?nolink |}}
===== Select voice =====

  * **No voice**  - voice commands are disabled
  * **Text-to-speech**  - Android text-to-speech automatic system. TTS voice can be set in **[[manual:user_guide:settings:lang_units|Language&Units]]** settings section.
<WRAP center round tip>
It is possible to download other voice sets from [[:manual:user_guide:locus_store|Locus Store > Features]].

===== Route re-calculation =====
==== AUTOMATIC ====

{{ :manual:user_guide:functions:navigation:naviset02.png?nolink |}}
Navigation route is recalculated automatically if the deviation from the former route is greater than the parameter **distance for recalculation**. If you don't follow the recalculated route, Locus Map will recalculate it **once again after 30 seconds**. You will need **internet connection** in case an **online routing service** is selected (e.g. GraphHopper Online or YOURS). For **[[manual:user_guide:functions:navigation:point-to-point#offline_navigation|offline routing]]** it is necessary to additionally download and install **BRouter** co-app and download **offline routing data**. There are 3 options:

  * **No auto recalculation**  - the function is switched OFF - Locus switches to guidance to the nearest point of the original route
  * **Point priority**  - Locus recalculates the route to the nearest transit (or 'via') point on the planned route. If there are no 'via' points, it recalculates the route to the final point.
  * **Route priority**  - used when you deviate from the original line and want to get back to it - Locus navigates you to the original line as soon as possible and on the nearest place - the line (route) matters.

==== MANUAL ====
Settings for manual recalculation that can be triggered from **[[manual:user_guide:functions:navigation#control_menu|navigation panel]]**.

===== Out of route notification =====

Check this option if you want Locus Map to warn you when you **accidentally leave your route**. Set the alert **distance**, alert **repetition** and **type of sound** (beep, voice…):\\ {{ :manual:user_guide:functions:navigation:naviset03.png?nolink |}}
===== Line style =====
{{ :manual:user_guide:functions:navigation:naviset05.png?nolink |}}
  * **Basic** - in default settings, the line width and color it is optimized for the best visibility. Anyway, it is possible to change them.
  * **Custom** - you can set all parameters of the line style Locus Map offers in its **[[manual:user_guide:tracks:management#style_editor|line style editor]]**
  * **Keep original** - when you navigate an already existing route (imported, planned, recorded track...) and you want to maintain its line style during navigation, select this option.

===== Advanced settings =====

==== Strict route following ====

Each route consists of a chain of routepoints (sort of breadcrumbs). This option navigates strictly from one routepoint to another. When you make a deviation, it tries to get you to the last omitted routepoint.\\ <WRAP important round>Keep in mind that this feature may come into conflict with your intentions e.g. when making unwanted detour and part of the original route is not accessible - it will keep navigating you to the first missed routepoint. If you want to skip a routepoint, switch it manually to the next **nearest point** in the [[manual:user_guide:functions:navigation#navigation_control_menu|Navigation control menu]]. \\ \\ **This feature does not work when Auto-recalculation with Point priority is ON**.</WRAP>
==== Maximum allowed deviation ====

Sets maximum allowed deviation from the route before switching navigation to guidance
==== Snap to route ====

Ignores slight inaccuracies of GPS positioning and maintains the navigation cursor position on the navigated route
==== Frequency of commands ====

Manually drawn or imported routes do not contain navigation commands so when you select navigation along such a route, Locus has to generate the navigation commands according to the shape of the line. This setting defines how often you are prompted of direction changes on the route: none - low - medium - high.
==== Two commands at once ====

When two turns of a route follow closely, Locus Map notifies of both of them at once. Unchecking divides the navigation command into two separate ones.
==== Stop navigation at route finish ====

When checked, the navigation is stopped and navigation panel removed when you get to the finish of your route 
==== Navigation cursors ====

Here you can select set of navigation cursors and set their size (50%-400%)
