I need nautical charts for inreach explorer se +. I need tour help.
I see you mentioned two different inReach models -- the inReach Explorer+ and the inReach SE+. If you have the inReach Explorer+, that model does feature mapping, however, no nautical charts are offered. For more information about the map types that are offered on the inReach Explorer+, reference the article, Preloaded Map Coverage for inReach Explorer+.
If you have the inReach SE+, that model does not feature mapping so no maps of any kind, including nautical charts, can be installed on it.
If you need an inReach device compatible with nautical charts, you may want to look into the GPSMap 86sci which comes pre-loaded with BluChart G3 Coastal Charts.
Although nautical charts are not available for the Explorer+ device itself, NOAA charts are available in the Earthmate mobile app. The app is free. It must be paired with an iR device, and you must be logged into an account with an active subscription. Obviously, this does require the use of the phone in addition to the device itself.
