When you call ask what the Broadcom BCM4750 chip does. It's the chip in the top left corner:

And I will say so as well. In fact SWMBO is currently stateside bimbling around the Monument Valley area in Utah using hers to navigate with and that has no SIM in it (which is sitting on my desk here at home). I fancy the cell phone network and wireless coverage is a tad sparse over there!

In fact 3G coverage in Monument valley is surprisingly good, down loaded the Telegraph there 2 days running.

How can there be so many answers to a simple question of fact? I'm still not clear if it's yes or no.

Along with a lot of other posters, mine works, very accurately, in the middle of nowhere with absolutely no chance of a cellular signal. Is that clear enough? :encouragement:

It does not have TRUE GPS, like you have in your Furuno/Raymarine. It has TRUE AGPS which as long as cellular coverage is availale your Navionics will work as you would expect your Raymarine to work in coastal regions.

Sailing west from Gibraltar, under sextant navigation. If you stopped half way and switched on your iPad 3g with Navionics and your Raymarine device. You would get GPS from Raymarine and your Navionics Ipad would not work without you manually entering your GPS data into it.

Ive bought it anyway, lets face it. We only need good chart info in coastal regions where ' big partly submerged rocks can ruin our day"

Cheers for the help.

AGPS it has TRUE GPS like my Geko. It does not. If you are in ANY DOUBT call tecnhical at Apple for confirmation.

This is complete nonsense.
The ipad2 with wifi and 3g has the broadcom BCM4750 chip. The picture I posted above is from an iPad 2.

No this is wrong.
The the 3G iPad will work as normal marine GPS unit without a cell signal.
The confusion comes about from the the poor term AGPS. This is assisted GPS. It works as a stand alone GPS but when within cell phone range it will also use this information to speed up /refine the fix.
The main use of this is when inside buildings etc where the GPS signal is poor. It does not need this cell phone signal for a fix it only helps the position signal.

The wifi only ipad is different it has no GPS chip and can only use the phone towers to guage an approximate position.

Or as you got bad advice consider a Samsung tablet instead - most of them have GPS even in the cheaper wifi versions, which avoids the odd Apple design constraint

That would be the AGPS chip not The type you have in your Furuno. I invite you to call Apple and we can all move past this.

I will concede yes it does give True GPS based on Cellular

Then please will you explain the magic by which it works for me and many others, when there is zero cellular signal present?

Given that he already has the correct answer given with evidence from quite a few forumites, I don't think you're likely to make any progress with this one. I get the feeling he will continue to believe his own gibberish regardless of the facts presented

I was going to post that I have used an iPad 3G in the middle of the blinking Atlantic, where there is no cellular signal, no wifi - AND THE GPS WORKS

But I won't bother because we are all wasting our time.

I don't need to call Apple. I have talked to Broadcom. They make the chip. It is a 24channel gps with some functions passed onto the host chips to keep it as small and fast as possible. The Assistance is used to speed up SV acquisition and TTFF when the almanac data is old and to correct multi-path propagation. It will work with no wifi or cell data as a standalone receiver.

Utter tosh. I've been out of sight of land, hundreds of miles from the nearest cell phone mast, no chance of a signal and the iPad works just fine, giving the same position as my Raymarine and Garmin from a cold start. What don't you get??? Are you more willing to accept the words of a tech numpty who's never used the iPad out of sight of his sofa or folks who've used the thing for real?

The information on AGPS is not 'utter tosh'.

I've bought it anyway and until I cross Biscay I have tech people telling me AGPS is cellular. I, just like all of you believe the IPad 2 3G to have true GPS using nothing other than the satellites above.

I asked the question because the tech Apple people stumbled me. Just 3 weeks ago I even convinced ( just like all of you convincing me ) a chap in Gibraltar that owned an IPad 3G that it had true GPS even sighting a Navionics website that it did.

Your right I call Broadcom!

The users stating 'the GPS found me and I don't own a SIMcard ' well that on reading up about AGPS is what I would expect.

Anyway it should arrive soon.

Sorry james but you are incorrect; I don't think it matters because after about 20 people on here saying it does have true GPS you still don't believe us, so I'll keep using mine and you keep using yours - maybe I got a special one with a secret GPS chip :D

Assisted GPS is really GPS+ - it shaves seconds off the cold start position aquisition time - but I'll never convince you so ho hum.

TBH I don't think there can be a much better informed confirmation that the iPad 3G works mid-Atlantic as per the OP's initial question!

Great answer: the one I was after thanks! It has GPS! The kind my Garmin Geko has but better.

Look chaps I only wanted to believe beyond all reasonable doubt that iPad 2 3G can be used as a life saving device at sea or in the remoteness of non cellular areas.

Cheers for all the replies: delivery is due next week some time.
