My new phone is a GalaxyS3 and is telling me the internal GPS is accurate to 20mtrs. I have tried it in my truck and it seems very accurate.So depending how accurate a time is needed maybe it doesn't need the external GPS ?

That's only a 1hz receiver though, same speed as most phones, you really need a 5hz receiver which are £60+

You can get the 10Hz Qstarz BT-Q818xt for £50 which seems to get good reviews from people using RaceChrono. Ive got a cheap and cheerful 1hz GPS rx and it was pretty rubbish really. It made it look like I was dirt tracking at Oulton Park more than I was on the track!

well ok but i can only go on what results I get and they are absolutely fine.

Well Slow, when you got your results, did you export them in anyway i.e. using RaceChrono2Avi or anything like that? Im due an upgrade on my phone in a few months (hoping for the Galaxy S4 if its out then) so maybe an updated GPS chip in that might help. Would be nice to see how your S3 compared to my S2
