Thread: Garmin Thailand Street Map v.9.0 (TSM9.0) Thai & Eng

No there is not, converting the .img works, but you loose name search :met:

Yes, you'll get lane assist capabilities on your unit (assuming the map has it). TSM9.0 does not have lane assist,
but CNSEA4.5 does.

Sorry, I don't have an English link. I assume you're in Thailand and you're using TSM9.0 or CNSEA4.5 with your unit.

First you have to make sure that your unit does not have the new S4 mainboard. If you just bought the unit,
it probably is and you'll get a brick if you flash it.

If your motherboard is S2 or S3 then you're safe. To check your board version, press the battery icon at the
upper right of the unit for about 8 seconds, you'll be in the diagnostic mode. The board version is next to the
unit model at the top of the screen.

And where did you buy your unit from? I want to know what firmware it is using at the moment.
You can check that at the about page on your unit.

Let me know and we'll go from there.

tuffy, here is the walkthrough. Please read the whole thing first before attempting to flash
your unit. If you do it as shown, I'm sure everything will be fine.

IMPORTANT:

- This is for 2x5w units only
- This guide is for mainboard version S2 & S3 only.
This does not work with mainboard version S4, you'll end up with a white screen
and brick your unit! (To check your board version, press the battery icon at the upper
right of the unit for about 8 seconds, you'll be in the diagnostic mode. The board
version is next to the unit model at the top of the screen)
- make sure battery is at least 75% charged
- Backup all your files before flashing
- Please use a quality USB cable
- Do it at your own risk

It is also a good idea to hard reset your unit before and after flashing. You can do this
by turning the unit off, press and hold the lower-right corner of your screen and turn on
the unit. Hold and wait until a popup message appear asking whether you want to
delete user data. Answer Yes and the unit will reboot. NOTE: Your saved POI will be
deleted. If you want to keep your POIs, backup the Garmin/GPX folder.


STEP 1: Preparation

1. Remove your Memory Card (if any) from your Garmin Unit.

2. If you have security lock enabled, disable it.

3. Connect your Garmin Unit to the computer using the USB Cable.

4. Delete GUPDATE.GCD from the Garmin folder (if it is there)

5. Delete the VOICE and the TEXT folder inside the Garmin Folder.
(If you do not delete the files, problems will occur after the firmware update rendering your device useless).
REMEMBER NOT TO COPY BACK THE BACKED UP VOICE / TEXT.

NOTE: This is because the voice files that comes with the US/EU units are not
compatible with Asian firmwares. The same is true with voice files that come with
Asian units - they're not compatible with US/EU firmwares.

6. After deleting the voice and text folders, disconnect the Garmin Unit from the computer.

7. If you've not done so, Hard reset the unit.

8. Then Switch OFF the Garmin Unit.

STEP 2: Converting 205w to 2W Series (For 205w only, Other models please go to the next step)

WARNING: This is a one-way process. You will not be able to revert back to 205w. The only
disadvantage known at the current moment is that you'll lose the ecoroute feature if you
later flash to US/EU firmware.

1. Download the following file.
[Only registered and activated users can see links. ]

2. Unrar the file.

3. Drag the file 082701000500en.rgn and drop to Updater.exe

4. Under Connection Setting, Select USB Device.

5. Slide and HOLD the Power Button of the Nuvi, then quickly plug in the USB cable to connect to the computer. (Continue to hold the power button).

6. The updater.exe will detect the USB Device with your model software and Unit ID. (Continue to hold the power button)

7. Click "Ok" on the updater to process the flashing.

8. Release the Power Button AFTER you see "LOADER" appear on the Garmin Unit.

9. Let it flash the firmware (Do Not Disconnect your Garmin unit from your computer) till it is completed.

10. Once the update completes, let the Garmin unit boots until the nuvi drive appears on the PC. Then disconnect the cable from the PC.

11. Verify that you have a US firmware installed by going to the "About" screen. The version should be v5.00

12. Repeat No.3 to 10 using the file 082701000280.rgn

13. Verify that your unit has been changed to 2W Series by going to the "About" screen.

----------------------------------------------------------------------------------------------------------

STEP 3: Enabling TTS (Text-to-speech) on the 205w or 255w EU (Other models go to the next step)

WARNING: This hack comes with a minor flaw. The boot up logo of your unit will change to a Chinese logo.
Actually there is a clean patch to solve this problem but I am not allowed to distribute it.

1. Download the following file.
[Only registered and activated users can see links. ]

2. Unrar the file.

3. Drag the file CHN_v270.rgn and drop to Updater.exe

4. Under Connection Setting, Select USB Device.

5. Slide and HOLD the Power Button of the Nuvi, then quickly plug in the USB cable to connect to the computer. (Continue to hold the power button).

6. The updater.exe will detect the USB Device with your model software and Unit ID. (Continue to hold the power button)

7. Click "Ok" on the updater to process the flashing.

8. Release the Power Button AFTER you see "LOADER" appear on the Garmin Unit.

9. Let it flash the firmware (Do Not Disconnect your Garmin unit from your computer) till it is completed.

10. Once the update completes, let the Garmin unit boots until the nuvi drive appears on the PC. Then disconnect the cable from the PC.

11. Verify that you have a CHN firmware installed by going to the "About" screen. The version should be v2.70

12. Copy GUPDATE.GCD from the nuvi205W_CHN_v290 folder to the garmin folder of your unit

13. Disconnect the USB cable and let the unit restart. It will update itself to CHN v2.90.

14. Verify that you have CHN v2.90 installed.

15. Delete the GUPDATE.GCD from the garmin folder of your unit.

16. You have enabled TTS on your unit.

NOTE: For 205w, if you later flash your unit to US/EU firmware, you'll not be able to use TTS.

11. Let the unit starts, and when it asks for the country, choose SINGAPORE or MALAYSIA.

NOTE: This is important because each country you choose gives you different feature set. For Thailand, choose Singapore or Malaysia
for the best features.

12. Verify that you have a SG/MY firmware installed by going to the "About" screen. The version should be v2.30.

13. Copy GUPDATE.GCD from the nuvi2x5w_SG_v2.60 folder to the garmin folder of your unit.

20. Copy the TEXT and VOICE files from the downloaded rar file to the garmin folder of your unit.

21. Hard reset your unit again.

22. Go to Diagnostic mode (pressing and hold the battery icon) to check that the ROM passes the test.

Note: A small part of these instructions comes from nuvi255w's blog.
