your quote (I dont know yet how to do the response to your quote thing)
"From some of the comments about iPads, I seem to be getting that WIFI only iPads do not have an internal GPS? Am I understanding that correctly? Someone also mentioned that I'd need a Verizon or AT&T version but I don't understand why? On my iPhone I just turned off the WIFI and put it in airplane mode and GPS/Navionics still works fine. Also, am I correctly understanding that the version 1 iPads don't have internal GPS?"
Ex Calif correctly responded and clarified my comment. The identifier in ebay for a usd Ipad 2 or above will give you the choice of "Wifi only" or "Wifi and 3g" by giving you in the filter these options. They will have many times a comment "verizon" or "Att" or "Sprint" or another vendor. This means that this particular Ipad is only capable of connecting to that particular vendor IF YOU WANT IT. Dont be concerned that you need a contract
because you do not
. This is only that this Ipad has an internal GPS and all the comments that you read in this thread about external GPS units are not necessary. The wifi only Ipad 2 version is available and does not have GPS internally. I just bought one exactly like you are seeming likely to do on ebay and I got an Ipad 2 with GPS from Verizon (but I again did not contract with Verizon in any way....) In the picture, I have the charger
cable plugged in and INavx
open and the 12v extension cord. If the door that allows me to plug
in the charger
cord is open, then I feel that this is not waterproof. Therefore, I made the comment for you to try to cover this possible water
entry by a plastic something ....like a small bag, tape etc. If you run the Ipad 2 with the navigation
running and the screen
on, it will last without a charge in my experience about 3-4 hours. With the charger cable plugged in and charging
Next, my comments about the charger and the extension cord pictured is if you are going to be using this at some time in the future in a situation where your nav station goes down, and you need to use this. All the comments about the battery
not working are true if your electrical system
goes completely down. My comments are for you to have a way if you don't have a female 12v outlet at your helm
in a male ipad charger somewhere down below and have the Ipad at the helm
. And last, an Ipad charges only at 2 amps so you must buy a charger that is for an Ipad or a USB connection that puts out 2.0 amps.
Send me a private note if you would like any clarifications.
