Converting Nuvi 2x5W Firmware to MAL/SIN Firmware

[evilhomura89]

So how do you find the accuracy now that you have flashed? Any difference at all? As for the voice files, you are right, the voice files used in this firmware are different from the US firmware although bearing similar filenames (voice part no. are different).

didn't really test the accuracy...i can't stand the unnaturally robotic voice, so i switched back to US firmware (in fact i hate TTS, so i used only the normal vpm voice)
and for some reason, i tried simulating routes looking for JCV but couldn't see any pictures of the junction, only names of junction on the left
LA is working fine

Ok, now to clear up some things. Did you perform STEP 2: Converting 205w to 2W Series (http://www.malfreemaps.com/viewtopic.php?p=71759#p71759)?

hi dvpro,
i'm did't do it for step 2 bcz , mention from peterk this step for motherboard s2 & s3 only. i just flash to RGN as above intructuction:

IMPORTANT:

- This is for 255w/265w S4 Board units only
(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. Even if your unit is from
Asia (such as Taiwan), please do not skip this step.

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 4: Flash the Garmin Unit to SG/MY Firmware

1. Download the rar files.
http://rapidshare.com/files/287879386/0 ... S.rgn.html
http://rapidshare.com/files/285264803/S ... _Texts.rar

Mirror:
http://www.mediafire.com/download.php?n05xjjk5yxy
http://www.mediafire.com/?lkezrzdrrnt

Download the updater.exe
http://www.mediafire.com/?mnzzj4ynhzn

2. Unrar the rar files.

3. Drag the file 082701000270S4US.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. 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 a different feature
set. For Asia, 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 v2.70.
[ tools -> Settings -> System -> About ]

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

14. Hard reset your unit again.

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

16. You've successfully flash your unit to SG/MY firmware.

Actually from what I understand, all Nuvi205W regardless of S2, S3, or S4 must be flashed to Nuvi2W firmware first. Even then, the instructions you pasted is for 255W/265W S4 Board units only, and yours is a Nuvi205W S4 Board. No wonder it did not work. Anyway, since it does not state anything about Nuvi205W S4 Board (or Nuvi2x5W), maybe this model it's not suitable to be flashed to Sing/Mal firmware to use JCV after all.

IMPORTANT:

- This is for 255w/265w S4 Board units only

For 205W S4, you'll have to wait just like what chaicka says.

I have successfully flashed my 255w to 2.60

However, when I tried to generate the unlock code by submitting my username, password and Unit ID, there was no response from the web page.

Anyone encounter such problem?

[dvpro]

If your attempts were within these few days, it may have been resulted from a downed server over the holidays. Similar encounters have been reported by a couple of MSM members over at MSM forum.

Ok, thanks for the reply.

Hoping that MFM come up with the JV soon.
