Phone gps

[shaungonemad]

Hi folks I have been playing with the gps on my phone and I have found that it is different than the gps in my boat I also have an old hand held that is the same co-ords as the boat wgs84. The phone is the same co-ords as the gps we have at work that we use for road chainages the only settings on the phone are for degrees and decimal. So I was wondering what system is the phone running and is there a conversion rate.
Cheers Shaun
