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.

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.

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).
... 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.

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.
