Updating WinCE 6.0 to Android OS on Chinese Sat Nav

This is my first post, please bear with me if I'm asking an obvious question. I am trying to update my WinCE 6.0 sat nav to an Android OS (I believe my current version is known as S100 and (I think) I am upgrading to S150)

Here's what I have been supplied by the manufacturer of my sat nav:

SD Boot Fusing Tool
2 x BIN files to be fused to the SD card; SD-bl1-8k.bin and u-boot_sdboot.bin
A Panasonic SD card formatter

I have followed their rough instructions which are converted from Chinese:

1. Format SD card to FAT32 format performing complete erase
2. Add the 2 x BIN files to the tool for fusing to the SD card. This is where I am stuck.

I am receiving the following error message "Can't Read MBR Sector from Drive"

To confirm the SD card is not the issue I have swapped SD cards, run chkdsk /f against the drive and used the Rufus tool to obtain the following log output:

Can anyone help me as I do not understand what the issue is. This is the first time I have attempted this type of thing.
