i try to download the map using the GMDL
then put inside the software mapviewer_v03 ~> map folder there
i try to use my GPS-290.. at night...
10~20.. to retrieve the satellite data.. to my psp...
then half and hour later.. can used already...
ai.... but i will upset on it..
1. VERY SLOW>>>> the software always said [SPEED WARNING SPEED WARNING SPEED WARNING]
2. Looks like the Google map GMDL is outdated for malaysia map,
cause i try to download the whole KL map.... but.. when i using gps.. while i am driving... the location gps dot on my psp screen there, is not exactly 100% same on the map there...
3. i hope sony malaysia have a own server to let GPS psp go very efficient, just like Singapore, i heard from my customer.. they paid SG 30 per month, using GPS there.. and is fast ....

".. how come malaysia still dont have .. sigh..
yupp it is very slow... but then again it is also not as power consuming as the normal GPS systems.
For the mis alignment thinggy maybe it is the sat signal is weak lah since you are driving in KL. GPS system tends to fail when you are not in the open area.
Well I doubt many will pay for that service when you can do the 1 time investment on other GPS systems.
As for the Penang map the size can vary one. Depends on how much detail you save.
