As luke said, there is no reason why ist should not work.
and to diffrentiate between ist generation and 2nd generation,
if you go for the cheapo ones that are sold at mostly wreckers or stolen goods shops ( sultan ka khon) in RWP you will mostly get crapy 1st generation one.
so get some name brand thingo and it should work fine , also make sure its fitted in the original position in dash as its straight and not in the consoles coz it will be at 45 degrees and will skip more.
2ndly it will also depend on your driving style and the roads you will drive on.
