Hey guys, My understanding is that later model iPads and iPhones that are not "WiFi Only" all have GPS receivers that are entirely separate from the cellular receiver/transmitter. So, the GPS receiver will work even if you do not have a cellular data plan or cellular service.
So, these devices do NOT need cell service to determine your position. However, you WILL need cellular service to download the map imagery or chart imagery itself if you have not already downloaded the map or chart imagery via wifi before your voyage. Hope this helps clear things up. This website has detailed technical data for all iPhones and iPads. http://www.everymac.com/systems/apple/ipad/index-ipad-specs.html Ryan Sent from my iPhone _______________________________________________ This list is supported by the generous donations of our members.
