What is SGMYMAL map?

[ianchong48]

Been asked to update maps on my sis's Nuvi 255W (localized) but am not familiar with 'localized' nuvis or how to update the offical Garmin maps with JV. My own nuvis (660, 760, 1490, 3590) are US & EU sets ....

Advice/directions needed and will really be appreciated.

- where can updates for SGMYMAL (with JV) map be obtained? Is this the Garmin NT map?
- which directory in the 255W should the .img, .unl and the .jcv be placed in?

Thank you in advance.

Maps for the 255W can befound here: Board index » Downloads » Free Public Downloads » Garmin (cGPSmapper). The most recent is the MFM-Garmin 130114.

Just extract, then place the gmapsupp.img file in the /Garmin folder, preferably in the SDcard. FYI, there are also no JCV or LA features that are currently supported by cGPSmapper compiled maps. Also, there are no unl files needed for these maps.

Thank you for your input. I am familiar with the CGS maps which do not support JV. I am using these in my own US & EU Nuvis. However, I have never owned a 'localized' Nuvi before and am not conversant with the relevant JV and Lane Assist issues. I am also not clear on the official Garmin NT, MSM-Garmin and our own MFM-Garmin mapsets as regards their individual capabilities/limitations or differences.

I did try (..unsuccessfully..) to update the 255W with maps on Garmin SG's official website but I think I encountered some kind of issue re the 255W not having sufficient memory (???) to complete the process. So I still dont know exactly what the SGMAYMAL mapset (which I am quite sure has JV enabled) really is - Garmin's own or one of the two more updated JV enabled mapsets produced in conjunction with MalSingMaps and MalFreeMaps.??

So rather than 'guess' and in the process risk 'bricking' my sis's localized 255W, I am asking for much needed guidance over here.

Thanks much.

First of all, SGMYMAL is not a map, it is a file containing Junction Views. This file belongs to Malsingmaps and not Malfreemaps.

You will get this file SGMYMAL.JCV when you download, for example "Malsingmaps Malaysia/Singapore/Brunei NT2012.40" map from Garmin Singapore website. This file works ONLY with Malsingmaps (NT). There is no single update file of SGMYMAL.JCV for you to download.

SGMYMAL.JCV should reside in the folder of GARMIN/JCV in your GPS device.
The other files of .img and .unl should reside in the folder of GARMIN in your sd-card.

Please note that I do not own a 255W local set but I believe it should be the same as a 765 local set of which I own.

Hope the above is of some help.
Cheers.

Hi colalite:

Muchos, muchos gracias..!! You've clarified exactly what I was so uncertain about. Whether that mapset (which includes SGMYMAL.jcv with the .img and the .unl files) is a Garmin product produced in collaboration with MFM or with MSM.?
So it's with MSM ... I get it..!!


However, I would like to explore the Garmin-MFM product as well. May I extend my original enquiry further :
What is the .jcv file named in the Garmin-MFM JV mapset..?? If it's name is different fm the MSM .jcv file (..and I almost sure it will be..) can I then install both the Garmin-MSM as well as the Garmin-MFM JV mapsets using different filename for the respective .img and the .unl files.??

I realise this will not fit into the small 255W memory. BUT I am now thinking that it is probably worthwhile actually buying a local (say 1XXX or 2XXX series) nuvi to take advantage of the increasingly rich JCV & LA content of the available official JCV & LA Garmin maps.

Map Files and JCV files are a match pair by version by release by name

The .jcv files will have different filenames for MFM and MSM. So, you can put both files in the GARMIN/JCV folder. However, you must not change their original filenames.
As for the .img file, you can have different filenames; one for MFM and another for MSM and both residing in the GARMIN folder of your sd-card. The respective .unl files must have the same filenames of their corresponding MFM and MSM .img maps.
Note that when you are using the maps in your device, you cannot tick both maps to use; this will end up with conflicts and a whole lot of mess.

Hi guys:
I understand. Appreciate you sharing your insight. I'm now gonna begin checking out Singapore-Malaysia JCV + LA capable Nuvis as an addition to my clutch of LMT-edition US & EU Nuvis. Right now gravitating towards a 2XXX but cannot help being very tempted to get a 3XXX unit - even though it's rather extravagant since I'm already using a US-spec 3590LMT with the trusty MFM CGS maps. I believe JCV/LA content in MFM maps is probably not yet as widespread as I would like but hopefully the pace of implementation will pick up.

Decisions .... decisions ....!! On with the fun.......
Thank you fellas,
