First post contains links to flashing files for devices with MTK chipset, i.e. HWID 1106 and 1104.
Feedback is welcome.

Yes, this is what I meant. Hope we understand the information of PCB unlocking soon and it become public. Think you have seen Saniksanik Deluxe video with unlocked Routes:

Spoiler: YT video

If you flash nuvi series 13xx to 1460 SG firmware of nuvi ,routes is available.

Didn't know that 1460 SG firmware gives Routes. Thanks. I know that Routes are unlocked if flashed with 1360/1460 JPN and with 1690 EU/US/TW/AU/CA firmwares.

Cheers,

Saniksanik merge SG firmware with US and webupdater dont work with this firmware.
If you explore firmware with hex editor you can change PCB number,but with every new update of firmware you must change again or your nuvi show software missing.
Saniksanik work like this.

@ lolypop000

Sorry, I can't understand. Can you give example which string changes the PCB number?

Thanks,

I suggest that PCB number is in firmware in crypted (so as ID-PID-SID for map ID in HEX) Garmin format like other similar numbers...
For example, HEX expresion for voice files present in body of that files - device find and show PartNumber in inventory,
<PartNumber>006-D0397-00</PartNumber> <FileName>English_American_.vpm</FileName>
<PartNumber>006-D0400-00</PartNumber> <FileName>Deutsch__.vpm</FileName>
<PartNumber>006-D0401-00</PartNumber> <FileName>Francais_European_.vpm</FileName>

I can confirm "Updated firmware for 12xx MTK ONLY! v4.80" from the first page link appears to work on my nuvi 1250.
I have the "Junction View" menu option available in simulation mode.
A quick test and all other functions work well.
Now all I have to do is find an actual "Junction" to "View".

I'm happy - well done dvazg!

PS. Can you please tell me the (presumably) Chinese words after "Garmin" during bootup?
Edit: Worked it out with GIR Editor.

Hi....i am having problem with flashing the 5.10 fw for US set and mixed with a 2.80 SG/MY fw....

It keeps hanging at the image not found screen and refuse to go on....

Anyone succeed in mixing the 5.10 US fw with 2.80 SG fw?

Thanks in advanced....

@robinang

You must take boot.bin from US firmware 5.10 and fw_resource.bin and fw_all.bin from SG 2.80.
Then you must change with rgn tool number of HWID and SWID to number of us boot.bin.

If you have boot.blk number 972 here is flash for you to convert US to SG.
Dont forget to change your folder VOICE and TEXT to voice1 and text1 and then copy to your unit SG folder voice and text.

Hey Lolypop000,

Thanks for the quick reply...
I did that but only to find the image not found error.

Something i found, the order for the fw_resource.bin and fw_all.bin is diff in the 5.10 US fw than the SG 2.80 FW....

Which order should i follow?
