Have a look at the pic I posted in post #26. You are talking crap. I use it all the time, no SIM. Try it sometime, trout. Then apologise. Or, get a REAL smartphone, and THEN apologise.

iPhones have had GPS built in since 2010. Like I said, stick to facts.

Edit: I think that you are still missing the point that the maps need to be stored on the device. Also, you might be getting confused with whart Apple called Assisted GPS, which used mobile towers to improve accuracy when using the first GPS chips. Not anymore, the chip in the iPhone is at least equal to that used in any navigation device you care to name short of what the military use.

I am talking phones Not ipads that come with a built in GPS receiver.
I have had iphones and samsungs post 2010 that won't give me a position if I am out of service.

All iPhone models (4, 4S, 5, 5C, 5S, 6, 6+) include a GPS chip. No iPo​d-Touch model has a GPS chip. All iPad models that have 3G or Cellular also have GPS chip and therefore behave like an iPhone for mapping purposes.

All I can surmise is it is the app you are using that needs a cellular connection. Not all apps get access to the chip, at least on the iPhone. Can't speak for Android. Won't touch one.

Maybe location services were turned off?

John is right iPhones and most Android phones have had built in GPS for years. They also take advantage of A-GPS ( assisted GPS) where they use the mobile towers to get a faster lock on position - but most do have a proper GPS module as well.

Good point, Mark. That may well be the culprit.

[bigwhistle][bigsmile] No prob. The day we stop learning is our last. Go and download some maps[bigrolf]

John, google maps are probably the most updated of all map providers.

I know, Nick, but I can't begin to tell you how often I've found them to be wrong.

As for Google, or Apple for that matter, I simply do not trust their maps and won't download them. Sure, they are great for casual use, but not if you are reliant on accuracy. Many times I have found them to contradict each other when neither was correct. They need another 5 years in my view. Or, they need to by tomtom or Garmin.

I have a vague memory of hearing that Apple Maps used tomtom mapping info to make theirs.

I've been using Apple Maps for driving around Sydney. Works brilliantly so far as I can tell and the traffic flow thing seem accurate too. My street sometimes clogs up and I've found that apple's 'red' for traffic jam lines seems to match reality to within a few 10's of meters.
