JSL3 I'm pretty sure the new iphone 3g has true GPS. I have one and it works quite well. It may use cell towers to get a general location so the GPS doesn't have to "work so hard", use extra battery power, etc. But it does have GPS. Here's a blog article that describes how it works. Link

BTW, I just bought the iNavX software last night ($49.95) and it looks great. I'll try it out on the water on Friday. I'll let you know how it goes.

tonybinTX Beej67 - iPhone 3g has true GPS. Time to upgrade!

beej67 As soon as iPhone gets real GPS, and not the "interpolate between cel towers" crap it's got now, I might upgrade, and get the App too, as a backup.

slokaj I think it was $49.95 for the app, the chart downloads are all free.

beej67 What does the iPhone app cost?

PalmettoSailor MacENC looks pretty neat, but I think I'll stick with my free Seaclear on a PC for the time being. MacENC has some nicer features and support is no doubt better but Seaclear offers about 90% of the capablity for 100% less money.

The author of iNavX for the iPhone also has GPSNavX (raster charts) and MacENC(raster & vector charts) for the Mac OSX platform. GPSNavX - Marine Navigation & Charting Application for OS X Works great with the free NOAA downloadble charts in the US.

Info on the iPhone version at iNavX - Marine Navigation & Charting Application for iPhone. There is also a review on

In addition, AyeTides for the iPhone & iTouch will be available very soon.

New iPhone gps/charting app!

As if you need another reason to buy an i-Phone, there's a new app that downloads government raster charts, and ties them to the gps capability on the phone. Plot courses, create waypoints, zoom in and out. Wonderful! I just downloaded the program, so I have yet to become familiar with it, but so far it looks great!

Anyone elese seen this?
