I've seen a few guys using the Iphone and Androids for navigation, but I was wondering if anyone has an Ipad set up as a chartplotter. I considered using my HTC Evo but i felt the screen would be too small, so I started looking at options for the Ipad So far, I have down loaded iSailor(http://www.isailor.us/isailor/index.htm) for my Ipad 2WiFI only. The app is free. You only pay for the NOAA maps you want, which was $5.99 for my needs. It took me a while, but I finally fiqured out how to pair the Ipad with the Android Evo to use the EVO as a Bluetooth GPS reciever. There are modules made by Dual Electronics and Garmin that pair with the IPad that do this but they are $100 or so. I also needed to jailbreak the Ipad to use an app called GPS Bluetooth Stacker ($5.00) available on Cydia (an alternate app source for Iphone and IPad) to allow pairing with the Android. Jailbreaking is not as scary as I thought it would be..lol. On the Evo I downloaded and App from meowsbox called GPS bluetooth (android market)($10) which sends your device GPS data over bluetooth. I wasn't too confident all this would work. I'm not a techy at all, but to my surprise for less than $25 my Ipad is functioning as a Large screen Chartplotter. I like the iSailor app because there is just one menu for settings, things like units of measure and map orientation, but the functions you use regularly like are right on top and everything functions with the Ipad motions like pinch and spread etc.. I'm still looking for the water proof case. As of now this Moxiware case http://www.moxiware.com/collections/ipad-cases/products/wp-ipad-waterproof-case seams like a good option and you can get a mounting from them as well as an accesory. If anyone has any input I would appreciate it.
