So So
Blue Chart Mobile by Garman offers a better chart product/resolution and Garman offers an IPAD Compatible Bluetooth GPS which picks up both the US and Russian GPS satellites making your IPAD cellular independent. Plan2Nav also doesnt appear to offer a seamless/on chart interface with Active Captain the way Blue Chart Mobile does. All in all its a good start for Jepperson but still a ways to go.
