Chris: There are a number of options available to you.
1. You could forget about the computer in the cabin
, and just run iNavX
on an iPhone
, or the new iPad
. I have no personal experience (yet) with this system, but all reports I have read about iNavX
are very favourable, and the company support is apparently excellent. There is some question about the accuracy of the built-in GPS
2. Install MacENC on your Macbook in the cabin, and link it to your iPad
in the cockpit
, via WiFi
. (I don't believe Bluetooth will connect your GPS
to the iPad yet - maybe second generation?) Connect your laptop
to an external GPS antenna/receiver. No mouse or keyboard required - keep the iPad in a large Ziplock freezer
bag during inclement weather
There are likely other options ...............
