Garmin has made available MalSingMaps (MSM) Malaysia/Singapore/Brunei NT 2011.10 (2011-Q1) for free update now.
You can click here to download the installation file of MalSingMaps Malaysia/Singapore/Brunei NT 2011.10 from Garmin server. The download file is split into 4, and you just need to download the file relevant to your Garmin GPS navigator:
- nuvi 3790
- nuvi 1250
- nuvi 1460, 1350, 765 or 255w
- nuvi 205 or 205w
For nuvi 255w, the installation program requires you to have an SD Card slotted in your GPS before it can proceed. It will install gmapprom1.img (42,128KB) and SGMYMAL.JCV (215,403KB) into your SD Card instead of the flash memory of your GPS. This is something new from all the previous nuvi 255w MSM updates. Anyhow, the gmapprom1.unl file is still updated in the flash memory of the GPS.
In fact, you can move gmapprom1.img and SGMYMAL.JCV back to the flash memory of GPS after the installation.
During the installation process, you'll be asked for the unlock key. The key is stored in the existing gmapprom1.unl file in your Garmin GPS navigator, which you can open with Notepad or any text editor. Just copy and paste the key to the installer when asked.
