unable to read chart using raytech planner

Francois,

Ntag is the title data encryption developed by Navionics for its chart cards and was introduced around 2009-2010. RayTech software development ceased prior to the introduction of ntag file encryption. Per the FAQ found here, Windows 10 is not compatible with the Navionics Multicard Reader is not compatible with Windows 10 (including its compatibility mode options). It is recommended that a PC running Windows XP, 7, or 8 be used with RayTech Planner/RNS 6.1/6.2 software. Alternatively, as indicated within the FAQ, Raymarine Voyage Planner software (replaced RayTech Planner) may be used for Planning Waypoints and Routes. Voyage Planner software supports Navionics ntag file encryption and does not require a proprietary memory card reader.
