function, but make sure you buy the 3G version. Not complicated at all, read the guide carefully.
To add a little more to this branch of the discussion...
If by some chance you have an iPhone or iPad that has no GPS or you are so far away from cellphone tower assisted GPS, you can get add-on modules that give you full independent GPS. Example: do a Google
search on "Bad Elf GPS". This module works with GPS apps like iNavX and I imagine it would be just as good for Plan2Nav as well (no personal experience there, just an educated guess). There are a couple other brands out there as well for iPad compatible GPS add-on modules.
The iNavX app has a lot of depth
to its features so its worth going through the help guide for it at Contents
For all the X-Traverse hosted USA, Canadian, international charts (Navionics, NV Digital, CHS, others -- but no C-MAP
format charts) available for iNavX via download from X-Traverse see the full lists for...
The main tricks to getting the app and charts to work
together are to (a) create the X-Traverse account, confirm it with the auto-sent email
X-Travese sends; (b) Get your case sensitive password perfect, probably just stick to letters and numbers, nothing too fancy (c) you may find Wi-Fi works better for downloading the charts than 3G cellular.
The downloads of charts typically take 30 seconds to several minutes depending on your internet
connection. The file sizes vary from a few hundred KB for raster charts, and about 5 to 70 MB for the Navionics vector charts. So most people will find they don't consume all their iPad memory, assumign they've downloaded just the charts they actually need from 1 or 2 or 3 chart collections. Once the charts are downloaded, no further internet
connection is needed, they stay installed as long as the iNavX app remains installed.
