Correct me if I’m mistaken, you have to purchase a cellular capable iPad in order to get the GPS chip.
You don’t have to activate it, regular iPad doesn’t have a gps chip.

I believe you are correct. You can also buy an external antenna like I did if you don't have the cellular iPad. Plugs into the charging port.

Garmin has a feature that allows you to clone the screen with an Ipad.
also the Ipad can be used to control whatever is linked to your Garmin, like your auto pilot.
I think it is Ipad only, you cant use a non Apple product (not 100% sure)

I bought a small Garmin as a back up, I think its a 7" screen and I can also repeat it to my iPhone.
I can also plot stuff out on my phone away from the boat and upload it into the Boat later.

I also have a non Ipad tablet with internal GPS that has Navionics on it that I use as a second back up.

The only limitations of the tablet and Ipad/iPhone are that they are not as easy to read in direct sunlight as an actual marine chartplotter.

There are sunlight readable and weather proof tablets available commercially.

Anyone know if the Navionics app has a look ahead function for the charts? I cant find anything o_O
yes you can look ahead w Navionics or course up, or north up.

I wondered why it had look ahead and course up?
The look ahead and course up seem slightly different.
The look ahead is instantaneous as you turn the device itself, almost like a compass.
The course up is the direction you are travelling in regardless of which direction the unit is pointed in.

I have tablet that has in internal GPS and is not connected to a network.
I have used the tablet on chartplotter well beyond cellular range.

I am not sure about my iPhone if it needs cellular to run the GPS?

both the tablet and GPS have uploaded charts into their drives.

By "look ahead" I mean having the boat icon further down on the screen instead of right in the middle, it lets you see more of where you're going and less of where you have been. my simrad plotter has it and it is a great function
I don't think you can do this automatically on a plotter, can you? Something like true motion it is called. I use an offset on the radar to get a farther look out on a smaller scale. But on a plotter it would need to know your heading. Unless, you can stop the ship center function and pan the chart to how you want it. When I use the Navionics on my iPad, I often pan the chart away from my location and with the heading marker, I can find a good compass heading to steer.

Yes Navionics (and Garmin) has an adjustable projected course line for current speed and direction.
