Yeah, what Pat said. :wink: There is a resolution difference between the iPhone version and the iPad version on the iPad. There is also a few minor differences in how each version interacts... i.e. if you pull up marina info on the iPhone version, you can just press on the phone number and it will dial the marina (obviously not on the iPad).
Gotta agree that if you are evening thinking about going into Canada, it is worth the very small extra money to get the whole she-bang instead of just the US charts.
The Navionics apps are so inexpensive, we have 'em on my Droid (Android version), Joan's iPhone (iPhone version) and the iPad (both the iPhone and iPad versions)... for less than $100. In other words, for less than 1/2 the cost of one measly chart area for the Raymarine C or E series CF chart chips... and you get Canada!
Best wishes,
