This lock also takes effect when OSM cards are involved.

Garmin has built in a locking mechanism in newer marine devices to prevent older Bluecharts (without G2) from being used (Message: "Karte nicht kompatibel" ). Maps that are displayed perfectly on Garmin outdoor or travel devices generally do have the same quality on marine devices and are therefore unusable. Without TYPE files, however, the priority of polygons cannot be defined. In order to display polygons, only a few clearly defined colours and textures are available. So far, Garmin marine devices do not support TYPE files (for freely definable symbols, colours and textures). Unfortunately, they did not implement lane assist guides or Bluechart Vision. For this reason, a partial support for NT and Bluechart (G2) was implemented. However, outdoor devices were designed to be used in a car or on a boat as well. The Bluechart version does not offer green meadows, brown fields or even tree symbols in a forest. All sea maps, either traditional Bluechart, G2 or G2 Vision, work without TYPE files, as these do not display particularly detailed or multi-coloured images on shore. However, Bluechart G2 Vision only works in combination

Only work on Garmin nüvi devices, whereas the very detailed and colourful topographic maps are meant for use in outdoor devices. NT maps with lane assist guides and traffic information New maps are only compatible with the device for the respective target group.

Over time, the various Garmin devices for car, outdoor and marine applications have evolved in different directions. Outdoor, by Mapsource + Multistorage (only 12MB) Portable two-in-one touch screen device for street and marine applications OpenSeaMap works on the following Garmin devices:Īll these devices should work for OpenSeaMap, also all the hand-helds and chart plotters in this list:
