Your nuvi 750 is a simple device. The gmapbmap.img is the base map ,the device won't work without it
Just replace the old gmapsupp.img on the SD card with the 1 you downloaded. Using the "Thanks" button were you downloaded it from would help.

Yes 5.40 is the latest Firmware

Garmin_Nuvi Reviewed by Garmin_Nuvi on 4th July 2021. Newbe - NUVI 750 Help I'm an IT guy in USAF so not afraid of doing this but want to be educated before moving forward. I've had a NUVI 750 for years and have been quite happy with it but would like to update the Maps to the latest available and learn how to do this. We also have a 2013 Tahoe and quite frankly I hate the GM Navigation - it often takes me on routes that do not make sense and how the Garmin would take me. So another reason I would like to be using the latest Garmin Map update available. 1. Last Rating: 5
