C-Map NT+ Vs C-Map Max

[River Cruiser]

I found the Jeppensen site to be difficult to navigate on my iPhone so I'll ask my question here. What is the difference in the NT+ and the Max cards? Also do they have 1 card that covers the inland rivers & the gulf coast? I just bought a Standard Horizon gps and want to buy the right card the 1st. time. A place to buy at the best price would be great. Thank you for any & all help

I think the MAX just covers a larger area. I use the NT and I don't think the Max is compatible with my old RL70. Give them a call they are very helpful.

Thank you for the reply, I bought the max card it covers the inland rivers & gulf, it has much more detail than the imbedded chart on the unit.
