Hello!
we are heading to Indonesia and have read that aa AIS sender is required.
We currently have a Raymarine 350 receiver and it appears we need to upgrade to an AIS 650.

Can any one help me with information about whether this is a straight swap and whether it will work with our E7 display and i70 Instrument
display?

Or maybe some one has a completely different and far better suggestion?

Thank you for any and all help.
Neill
