Converting Nuvi 2x5W Firmware to MAL/SIN Firmware

[drsec]

Brothers,

Now that I have taken the plunge to over-write my Garmin 255W US 5.0 firmware with the MySg 2.6, I am able to conclude that from my point of view junction view is LESS useful than it has been made out to be because of the following reasons:

1. The picture is too small to be seen clearly from the driver location when the device is placed at the usual location at the center of the front screen.
2. The picture is a little too dark and fuzzy.
3. In the cases I have seen, the picture is not reflective of the real life view you are seeing in front of you. It will take you sometime to decipher the picture before it makes full sense of it thus distracting you from your driving.
3. It appears for too short a time.
4. For the moment there are too few junction with junction view.

I must warn everyone of the following:

1. Doing this will void your warranty.
2. I have not found a way to revert back to the US 5.0
3. Junction view is NOT available in MFM for Garmin
4. Junction view is available for Garmin in MSM, so you will have to download and use MSM, if you want JCV
5. MySg 2.6 firmware has only very limited voice and the ones in English is with TTS. There is none in English without TTS.
6. I am not sure if the MySg 2.6 JCV will work with JCV in other maps e.g. US, Europe and Australia etc.
7. You will lose the Ecoroute feature of US 5.0.
8. MySg 2.6 only provides JCV but not Lane Assist.

So decide very carefully before proceeding.

Actually Nuvi255W local version can use English_American_.vpm. Although the latest firmware does not come with English_American_.vpm, the original unit comes with that non-TTS voice.

Correct but in order to flash it with the new firmware, it requires one to remove all the voice files.

Not true, the updater requires removal of some TTS voice files only.

"2. I have not found a way to revert back to the US 5.0"
I was using neadrenalin's fw_nuvi2x5w_id0827_en_v500+tracklog_sd firmware before I flashed with the 082701000260.rgn file ktan2 posted.
I was able to flash from the 082701000260.rgn file ktan2 posted, back to neadrenalin's fw_nuvi2x5w_id0827_en_v500+tracklog_sd by renaming the rgn file from 082701000500en_sd.rgn to 093001000500.rgn.
Do so at your own risk, but it worked for me.

"4. Junction view is available for Garmin in MSM, so you will have to download and use MSM, if you want JCV"
For me, Junction View worked with Malsingmaps Malaysia-Singapore-Brunei NT 2009.5 and Junction View + Lane Assist with City Navigator Singapore-Malaysia NT v4.02.

"5. MySg 2.6 firmware has only very limited voice and the ones in English is with TTS. There is none in English without TTS."
English_American_.vpm (non-TTS) works OK.
The only voice file that gave me problems after flashing with Sing/Mal version was if I put English_British_.vpm (non-TTS) back into the Voice folder. If that was there, my Nuvi 255W would keep rebooting.

"6. I am not sure if the MySg 2.6 JCV will work with JCV in other maps e.g. US, Europe and Australia etc."
I could not get JCV to work with City Navigator North America NT 2010.1 (but Lane Assist did, and that was my main reason to do the Sing/Mal flash).

"8. MySg 2.6 only provides JCV but not Lane Assist."
The Sing/Mal 2.6 flash provided me with Lane Assist on both City Navigator Singapore-Malaysia NT v4.02 and City Navigator North America NT 2010.1.
