That was a hypothesis rather than anything else - something that might explain why I was getting more reliability issues than other people. Alternative theories were that I had mine mounted by the door pillar, so got worse reception than those who mounted it in the middle of the dashboard, or... that I am simply fussier than most. > Both of ours are 3GSs. Mine is great, hers less so. > Running both together they show a different position! The more I read about this, the more I'm convinced that some iPhones have slightly wonky GPS chips. And I think mine is one of them. I'll have to check it against Hannah's at some point. -zoara- -- email: nettid1 at fastmail dot fm

Also trial it without the phones being in a powered holder - all the holders I've used mess up the GPS signal to a greater or lesser extent.

Ah. Now *there's* a likely culprit. Mine's always powered, yet most people I've discussed it with have complained about how quickly sat nav drains the battery... I can do that without bothering Han as well (she uses her iPhone almost as much as me, so finding some time to play with both might be tricky). -zoara- -- email: nettid1 at fastmail dot fm

It does, drain in 3-4 hours with a continuous GPS monitoring app like tomtom. But for comparison testing of GPS signal reading, you need to do like for like, and I suspect the 3G and 3GS have their GPS aerials in different places which will be differently affected by the wires in a powered holder. (It's even worse if your powered holder does FM transmission to the car stereo) Cheers - Jaimie -- Actually, the Singularity seems rather useful in the entire work avoidance field.
