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 night I connected to Garmin Express and updated the software to v5.40 (would this be the Firmware?)
2. I backed up my Favorites to my PC
3. I backed up the gmapsupp a friend put on my SD card back in 2017
4. I downloaded gmapsupp(Lower 49) to my PC
When looking in the Garmin folder on the actual device I also see a file named (gmapbmap) (is this the original map loaded from the factory?)
If so I'll also back it up.
Do I need to replace this file with the the (gmapsupp (lower49) but name it (gmapbmap) or just replace the old file on the SD card with the new file?
In another folder within the device named - what are these files?
RemoteSW:
006B047800.BIN
006B048201.BIN
006B048201.sum
006B055301.GCD
006B063000.GCD
006B073300.BIN
006B073300.GCD
ExtData:
006-D0952-01.bin
006-D0952-02.bin
006-D0952-03.bin
006-D0952-04.bin
Is there any other files or updates I should be looking at?
I appreciate any help and guidance.48cj2a Reviewed by 48cj2a on . 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.

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
nuvi 7xx (GCD file) 006-B0754-00 Release 5.40
(8842 Kb)
The RemoteSW folder contains the FW/SW updates files you just installed with Garmin ExpressLast edited by Garmin_Nuvi; 4th July 2021 at 06:20 AM.
Unless you are a "New" member, having used the Thanks button regularly is the quickest way to get help.
