26/6/2025: New version 4.0 available check what's new
ScanNav Compagnon is an Android version issued from our knowledge on
developping the Windows version of ScanNav, and on users needs. Version 4.0
is compatible with all Android tablets and phones from version 5 (Lollipop) to the latest version known to date (16 - Baklava) and for all processor types (ARM/Intel/MIPS).
Note that Android versions 4 (Ice Cream Sandwich, Kitcat, and Jelly Bean) are only supported for older versions of Companion, up to version 3.0.
This application is dedicated to charts from our Raster SnMap
offer.
It is completely free of charge for ScanNav users who already have a Raster SnMap chart pack.
Users wishing to use only the Companion version for Android just need to acquire the charts.
Main functionalities are:
- Very fluid graphic rendering of charts in Seamless mode.
- Intuitive ergonomics with multi-touch.
- Creation of waypoints and routes.
- GPS Navigation with recorded track, target waypoint followup, and configurable repeat displays (Speed, Heading, ETA, etc...)
- Usage of internal GPS, or any external NMEA183 source via wifi (lets you run on low cost tablets without integrated gps) (wifi support from version 2.9)
- Management of objects data bases (wrecks, ports, etc...) in layers, with Search and Filter capabilities
- Auto-Save and GPX file import/export
- Interface available in French, English, and German (and auto translation for Spanish, Portuguese, Italian)
