 The **[[manual:user_guide:tracks:planning|Route Planner]]** and **[[manual:user_guide:functions:navigation|Navigate to]]** use services of route-generating engines called **routers**. The router generates a route based on selected profiles and their parameters. Each profile relates to an activity (hiking, nordic skiing...) or a means of transport (MTB, gravel bike, car...).

+You can use three routers in Locus Map 4:

-routersLocus Map uses for route planning and direct naOffline navigation is essential for any outdoor traveling. Bad or even no data signal in mountainous, rural or otherwise deserted areas makes online navigation useless. Locus Map offers its own **offline LoRouter** and also possibility to use an **external router - BRouter**.
-===== LoRouter Offline =====
-<wrap info>Available only with **[[https://www.locusmap.app/premium|Premium Gold]]**</wrap>
-The most sophisticated router of the app. It contains many routing profiles with additional configuration.
+LoRouter offers **9 routing profiles** divided into four categories:
-==== Profiles setup ====
+==== Walking ====
-{{ :manual:user_guide:functions:navigation:naviset10.jpg?nolink |}}
+  * {{:manual:user_guide:ic_type_walking_alt.png?nolink&30|}} **Walking** - perfect choice when you want to get the shortest way from one place to another on foot. Ideal for use in cities.\\ \\
+  * {{:manual:user_guide:ic_type_tourist_alt.png?nolink&30|}} **Hiking** - choose this when you need a route for a hike. This profile prefers hiking trails, and forest paths and doesn't evade hills.
+=== Additional parameters ===
-By default, LoRouter Offline offers 7 **basic profiles**. Each profile has additional setting option:\\ {{ :manual:user_guide:functions:navigation:naviset09.jpg?nolink |}}
+Both walking profiles offer the **wet conditions** option selecting less muddy surfaces where possible.
+==== Cycling ====
+  * {{:manual:user_guide:ic_type_cycle_alt.png?nolink&30|}} **Touring** - a basic bike profile preferring cycling paths and less hills for a comfy ride. Top choice for long-haul bike tourists.\\ //Aditional parameters:// you can allow or disallow **ferries** and **tunnels**\\ \\
+  * {{:manual:user_guide:ic_type_mountain_bike_alt.png?nolink&30|}} **MTB** - a profile for mountain bikers of all styles and skill levels. Basically, the profile prefers paths, tracks and trails and doesn't evade climbing. \\ //Additional parameters:// **Terrain level** - you can control the difficulty of the route based on its surface character, gradient and elevation profile. 5 levels are available - smooth, rolling, varied, technical and rugged. You can also dis/allow **ferries** or turn on **wet conditions** when you are heading out after rain.\\ \\
+  * {{:manual:user_guide:ic_type_gravel_alt.png?nolink&30|}} **Gravel** - profile preferring gravel hilly roads and tracks with compacted surface.\\ //Additional parameters// - besides **ferries** and **wet conditions** you can allow/ban **stairs** on the route.\\ \\
+  * {{:manual:user_guide:ic_type_road_bike_alt.png?nolink&30|}} **Road** - top choice for fast riders preferring tarmac roads.\\ //Additional parameters// - besides the **ferries**, **tunnels** and **steps** you can turn on/off **cycleway** preference
-You can change the profile selection:\\ {{ :manual:user_guide:functions:navigation:naviset11.gif?nolink |}}
+==== Motor vehicle ====
+  * {{:manual:user_guide:ic_type_car_fast_alt.png?nolink&30|}} **Fast** - basic car profile for the fastest routes between two destinations.\\ \\
+  * {{:manual:user_guide:ic_type_car_short_alt.png?nolink&30|}} **Economical** - profile for the shortest routes with low-speed limits for economical gas consumption
-**Advanced settings** - it is also possible to map a custom profile on an extisting in-app profile
+=== Additional parameters ===
+Both car profiles allow for control of **ferries**, **tolls**, **highway** access and **unpaved roads** for those with terrain vehicles
+==== Other ====
+  * {{:manual:user_guide:ic_type_cross_country_skiing_alt.png?nolink&30|}} **Cross country** - profile generating routes along marked and/or groomed ski tracks. Fully functional primarily in winter sports resorts. This profile has no additional parameters.
+==== Warnings ====
+LoRouter generates **warnings for various pitfalls on the route** – for challenging terrain, heavy traffic, barriers, tunnels, unprotected railway crossings, and so on. And that’s both in the route planner and in the quick route calculation for direct navigation to the destination:\\ {{ :manual:user_guide:functions:navigation:warn01.jpg?nolink |}}\\ Some warnings have **three color-differentiated levels** – from the least to the most serious warning:\\ {{ :manual:user_guide:functions:navigation:warn02.jpg?400 |}}\\ If a warning concerns entire sections of the route, e.g., challenging surfaces or heavy road traffic, it also has a **zonal variant**, so you know exactly which part of the route to be careful on.\\ {{ :manual:user_guide:functions:navigation:warn03.jpg?nolink |}}
+<WRAP center round tip>
+The display of warnings can be further configured in the **[[manual:user_guide:settings:points_tracks#route_warnings|app settings >>]]**

+The offline version of LoRouter uses offline routing data. We strongly recommend downloading it in advance or you'll be prompted to download **additionally while planning a route**. You can download it either with the **[[manual:user_guide:functions:navigation:settings#lorouter_offline|data downloader]]** in settings > Navigation > Router\\ {{ :manual:user_guide:functions:navigation:naviset16.jpg?nolink |}}\\  or as an additional part of LoMaps - routing data is a **part of every LoMap package** - you can download it from **[[manual:user_guide:locus_store|Locus Store]]**:
   * open Locus Store
   * find a LoMap of the desired area

-<WRAP center round tip>
+==== Profiles ====
-BRouter remains set as default also for route drawing in the [[manual:user_guide:tracks:planning|Route planner]]
+By default, there are a few profiles available for BRouter in Locus Map. But all of them are editable and you can add more profiles from the **[[https://github.com/abrensch/brouter/tree/master/misc/profiles2|BRouter repository]]** or **[[https://github.com/poutnikl/Brouter-profiles|other sources]]**:
+  * **Store** the downloaded .brf files into ///Locus/router/profiles2// directory
+  * **Edit**: long-pres a selected profile in the list and tap Edit on the popup:\\ {{ :manual:faq:router01.jpg?nolink |}}
+  * **Add**: tap **+** button in the profile list:\\ {{ :manual:faq:router02.jpg?nolink |}}
+  * fill in the **icon, name, category** and select **source** (.brf file):\\ {{ :manual:faq:router03.jpg?nolink |}}
+  * tap **SET**
+<WRAP center round important>
+Not all .brf files in BRouter and other repositories are compatible with Locus Map.
 </WRAP>
-==== Advanced options ====
-Although BRouter user interface looks quite simple, the app offers quite a lot of various settings, creating custom navigation profiles etc. A rich source of info and tips is this [[https://github.com/poutnikl/Brouter-profiles/wiki|wiki-blog >>]]. BRouter provides also a [[http://brouter.de/brouter-web/|web app]], enabling route planning on a big PC screen and consequent export to GPX file and then to Locus Map.
