Thread: 2xxx and 3xxx series enable features application

@michaeloli
No sorry, it won't work for 2xx9 devices.

@fdesouza
I suggest you follow the steps described in [Only registered and activated users can see links. ] ensuring that you substitute appropriately for 35xx (name the folder containing update.txt and ldr.bin as 1258 to match 35xx HWID and be sure to use the ldr.bin from the 35xx firmware). In the modified 140.bin you can check every feature EXCEPT ecoRoute HD and ecoRoute Purchase. If you get stuck post again with a request for it and i'll make the kit for you. Note if you have a senior model 3590 that the only available extras will be Video Player and MP3 Player.

@Butters
After doing some research, I was finally able to make the modification.
Thank you very much for your help

Hello:
All links are dead. Can anyone help me add the Player on a Garmin 3590LMT?
Please....

• Ensure you have US/EU model 3590 with HWID 1258: [Only registered and activated users can see links. ]
• Ensure your US/EU 3590 has latest firmware Version 8.50 (connect to GarminExpress and update if it has a lower version)
• EXTRACT the Flash Kit ZIP file directly to a CLEAN microSD card (look behind Spoiler below)
• Ensure your device is fully OFF, not just in standby mode
• Insert the card
• Power on (if the battery is low, connect to an external power source [NOT a computer USB port] which will power it on)
• "Loader"/"Software Loading" or similar message should appear on screen during start-up
• Wait for it to finish the flash and re-boot itself, then remove the card.

"Apps" screen should now have Media Player and Video Player icons. Keep the files from the card in a safe place. In the card root you should now additionally have '41_BUP.bin' and '140_BUP.bin'which are copies of your device's non-vol and features regions. In the 1258 folder there will also be a new file named 'last_id.bin' which must be removed before re-using the files or it will prevent further flashings.

Disclaimer: All care taken in preparation but no responsibility accepted if your device is damaged. Follow the above instructions EXACTLY.

Most links are still down, so I have some quesions.
My unit Nuvi 2455LMT. B1371-00 8.30 PCB105-01925-02 TZMap 37.00
1 Does this still work in 2024,almost 2025?
2.After these changes will garmin still update fw and maps without any problem?
3.Where can I find the original firmware for this unit?
4. Mainly I'd like the asr to work, will the asr files and xml download to the unit after updating?
Thank you very much

Thank you for the fw link. I believe I have the correct file.
As for my question number 2, Was wondering if after adding features, would Garmin firmware update remove them, if applied?
I have not opened the unit yet but was curious if there were even a microphone to be able to use the ASR? Garmin Manual covers 24xx and 25xx and quotes "Voice Command is not available on all
models, or for all languages and regions."

Thanks Neil, that clears things up a bit. Seems it would not be worth the effort to add a physical mic and then lose or have issues with the built in tmc.
