BirdEyes images can be restored AFTER flashing new firmware

Instructions

Show Spoiler

Unpack contents to fresh SD card formatted FAT32
Ensure your device is fully OFF (not in standby), insert the card into your device and power on.
"Loader" will appear on screen for a while then the device will boot up when the flash of patched firmware is complete.
Your device may reboot its self during the process just be patient.

Your SD card will have a new file named 154.bin this is a backup of the device's non-volatile memory region and may save your device later if needed,so keep a copy of it somewhere safe.

Sadly it looks like this download link is broken - it's been down for over 24 hours. Is there an alternative location for download ? Thanking you in advance !!

Hi, I have this device:

Code:

        <PartNumber>006-B1749-00</PartNumber>
        <SoftwareVersion>450</SoftwareVersion>
        <Description>nüvi 65</Description>

I think is this:
Model: Nuvi 65/66 | HWID: 1749 | SWVS: 450 | MAP: Yes | GMA: Yes | MSV: Weak | GVS: Yes | File: nuvi65_66_450.gcd

Original Map in the device is CN Europe NTU 2016.10

It can be patched to accept any map?

I have try to find if anyone requested this patch before, but I only see newer versions of software

Thanks a lot!!

I'm sorry but the Garmin Edge 530 has Encrypted Firmware and it is not possible, at the moment, to apply any Patch
