I Have A Garmin Nuvi 255w Gps, Is It Possible To Get It To Output An Nmea Gps String ?
if you mean like a constant output of data on the USB connector… well I don’t think so. (but there are cheaper versions of GPS only receivers that can do that, sending data through USB or Bluetooth).
if you only need to record NMEA data in a .csv (kind of) file, then you’ll have first to “unlock” the device, then to install a software that can do that (visualGPS for example).
