Jason Ooi...what Nuvi 205W you haved? is it local My/Sg or imported unit from other country?.if u haved local unit,there should be no problem to download map from Garmin.sg...like mentioned by Garmin.sg website below.

http://www.garmin.sg.comHow to find the serial number ?The serial number is a 8-10 charaters long and contains no spaces or dashes. It is on the bottom of your unit, either inside an outlined box(remove mounting bracket to view) or above the gold contacts.
BTW,if u just need to download..it's no need to key-in the serial number..just click "
I AGREE AND START DOWNLOAD ",the map file will download in a second,but you will have a problem later to install the map onto your GPS unit,it will ask the " UNLOCKED CODE " thats you need to generate it from website before,if you dont have sufficient privileage..let say ( IF YOU GPS UNIT IS NOT LOCALLY MY/SG ) so you cant unlock the map set by using Garmin Installer,you need to buy it from Garmin International-
http://www.garmin.comAlternate is,use MFM map,this MFM map much detailed from official released,the keveat only this MFM map just dont have JCV file for Junction View ( JV ),
But there is no need to use this function of JV if your GPS unit is not local My/Sg,because just local unit of My/SG firmware ( FW ) will work this JCV file,if your GPS unit is using USA FW like version V7.60,there is no options to activate JV functions.

Hope this help,TQ N regards
