a) is it worth the money? is the connection always available in Malaysia here?

Is it worth the money depends on how much you use it ans what you use it for. Connection always available? You think it's somehting like tmnet streamyx ah ?

c) wats the difference between 16 channel and 32 channel??

for you usage ...no difference. It's better to look at sensitivity.




b) my friend told me that GPS shows the road and direction, but dangerous to use cuz some roads are 1 way street, GPS doesnt tell. true or false? do advise, and the GPS programme that u use

I donno about that, but i've been using gps for unfamiliar places. Never encountered that problem. You should worry more whether the map is updated or not.
