Apple had huge balls (and bad judgment) when they decided to call their techs "geniuses".

My iPad GPS works without a WiFi or cell signal. When it has WiFi on the boat it is always from a Verizon MiFi, which means the device isn't getting effective WiFi position data.

The "geniuses" don't know what they're talking about. The apps might not work properly without a connection, but the GPS works.

What about the power draw, and how do you hook it up to say a 740s? with another expensive network hub?

Please Note: This kit includes a household AC power-over-Ethernet (POE) adapter. If users are unable to use the included adapter on the boat, they must purchase a POE adapter that supplies 12-15 Vdc and 0.8 A. Additional items needed for installation are 2 shielded Category 5 (CAT5) Ethernet cables (not included).

Draw is almost an amp??? Is it really worth it if you already have a GPS capable tablet and Navionics HD?????

I can say with certainty that the iPhone 4/4S/5 and iPad 3G/4G models include a GPS receiver which does not need a cell or WiFi connection/service/subscription to function.

"Location Services" can use WiFi or or cell connections to assist in determining the iDevice position, but they are not required.

Most nav apps will display some sort of position accuracy indicator. In the case of iNavX, "HPE:" (Horizontal Position Error) is displayed in the Instruments view or banner. I typically see under 16'.

Quite simply, the "apple guys" are wrong. The iPad (and iPhone) have fully-functional GPS capabilities, as do many other tablets and smart phones. Your so-called "genius" was probably fixated on the idea that you need cellular data to use the Maps programs (like Google Maps ... but worse). You need the cellular connection to pull the map data, but that is unconnected with the GPS.

Land an,
Don't believe everything you think.
The Cellular iPad has a built in GPS which works without cellular or WiFi.
Been using and iPad offshore for years with no problems.

The GPS in my iPad has gotten me from New York to Florida without wifi or cell data on.

I am a little bit lost.... But any tourist in the USA is!

So the apple guys steered me wrong! Well if that doesn't beat the band. Back considering IPad again. People tell me it's hard to read in the sun- apple guys said no problem there. What about that one?
The new app looks nice. Just downloaded it.

First time in a LONG time I've wished I was still an iPhone guy. Does anyone know if plans are to have an Android version? I see most of there stuff has both. Or does anyone know annother app for Android that offers Explorer Charts?

To me that eliminates the iPad.
Am I wrong?

Yep...you are wrong .

It is ok in the sun, however if you want to use it with polarized sunglasses you have to hold it in landscape mode.

I found my iPad almost impossible to see in direct sun. Indirect sunlight was acceptable. Best if you can view it in the shade. We mount ours underneath the dodger when underway.

Just to clarify the gps question. Apple does offer iPads without GPS. You need to get the cellular data version to get GPS. They do offer a line of wifi-only versions.

If you have an iPhone or an iPad, this is the product to buy
If you don't have an iPad, BlueChart Mobile is more than enough reason to buy one (get a cellular, 32 GB, latest model, iPad 4th gen).]

I see that you need a cellular service (like Verizon or ATT) to use the 3G function of the iPad. Does anyone know how this works outside the U.S.--say in the Bahamas or the Caribbean?

well mine worked fine 400 miles away from land. The main reason is the confusion over the term "assisted GPS", This means the time to first fix, is accelerated by using the Wifi/ cellular, first by speeding up the maths involved in solving the first fix equations, and also that the ephemeris can be download over the internet if available , rather then the quite slow data rate from the satellites.

So assisted GPS is better then ordinary straight GPS, not worse. Assisted GPS has been around for a while ( car tracking etc)

Of course to further confusion , is that Apple bundle the GPS with the cellular, convincing people thats its needed.
