Choosing a GPS help.

[Kracker Jack]

well the facts are in!!!! After having a 6 page long thread on The Hull Truth about the Navionics USA app, I have found out that yes it will work out of wifi and cell range. here are a few comments from some electronic geeks over there.

#1 The iPad 3G or iPhone 4/4S GPS receiver does not need a cell or WiFi service/subscription/connection to function. Apps such as iNavX and Navionics store the charts locally on the iDevice so they only need to be downloaded once.




#2 The HTC Evo has an internal GPS. I use it quite frequently while flying where there is no cell phone or wi-fi signal. The phone specs ( http://www.htc.com/us/products/evo-sprint#tech-specs) show it has GPS and aGPS. aGPS stands for Assisted GPS which means it can use a cell or wi-fi signal to lock faster on satellites.fshmn,



#3 I have an iPhone 4 with the Navionics app. The chart plotter works in the North East canyons 90-100 miles offshore.

I can't tell you how it works, just that it does.

Yes

Does the Navionics App connect to the Iphone internal GPS receiver? Yes
Again, assuming from your statement that the Iphone has a GPS receiver. Yes
Or will I have to integrate the Navionics maps into the Iphone GPS App? ?? Plug n play, download the app, use the app on a wifi connection to download section(s) of the chart(s) you require...

If so, $10 is a cheap backup GPS on my boat. - Yes!
