GPS Repair Problems? Ask a GPS Technician for Answers ASAP
Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I'm not sure quite what sort of map files your Humminbird device would accept - since you have not mentioned its model #.
But, I think that Navionics provides what you are looking for:
and also look under the 'Mobile' rectangle at the top of that page.
(If this answers your question, please rate my answer, so that this case may be closed. If you need more information, just Reply To Expert and let me know. Thanks.)
That page seems to indicate that these Navionics maps are designed for Chartplotter or MFD devices, not iPad.
But, that page links to
which (Navionics Boating) is indicated as an app for Android and iPad.
Whether that will 'show you your position', as opposed to allowing you to browse the Navionics maps, is a question. Chartplotter devices either have GPS function or are attached to a GPS device which tells the Chartplotter your position... but unless your iPad has GPS function AND that is linked into Navionics Boating to indicate position, is a point I'm not quite certain of. It *might* only be a map-browsing utility, so proceed with observant caution in purchasing, and Caveat Emptor.
I'm sorry it didn't seem as good an experience as it should have been.
Did you settle on Navionics, or did you use something else?
