Unfortunately, the O2 original cable does not work with this charger. I had to get another of the same cable and do the short pin 2&3 method.
You can mod the carger itself but by doing so, it will no longer work on other phones (e.g. Apple products).

So far I have not come accross any car cradle/charger which works with the O2 out-of-the-box.
Not sure whether KL sells this or not. I got mine in Miri, Sarawak. No harm hunting around though as Capdase is quite a popular brand...

Nice! Too bad I can't try it right now.
Apparently, their server is overloaded. Guess there too many of them downloading at once...
