well check your GPS unit if it is connected properly, if you inspect the bottom part of the unit, you should see two gold pins on left and right of the USB connector. If one of them dont make contact into the unit then the unit does not receive power.
if one of them are shorter than the other try pulling it gently down a little to even out the lengths.
to get the map for KL, just use the GMDL (Global Map Downloader Tool) supplied in the Mapthis download RAR file. Open the Global Map Download Tool.exe in the /Debug folder of the GMDL folder. Create an empty directory on your desktop with a name that starts with _ . i.e, (_KL). Then in the space above the map tool state that directory. Make sure you are connected to the internet to download the map (duh). The program will automatically open up Google Maps, navigate to the area you want to download and then click Download this map at the top left. It will then slowly load the area you selected in google maps. Confirm your selection and then proceed with the download.
IMPORTANT! you need 2 or 3 system files from your psp firmware (usbacc.prx, (something else).prx and one more that I cant remember. Without those the program will not start.
I still havent got the psp to tell me to turn left or right when on the road, I bought the Dragon car stand to fit my GPS but it doesnt fit. Still need to mod the car stand to make it fit.

Other than that yeah the GPS works fine in malaysia now, thanks to google maps updating our roads!
