I have a Raymarine
C series system and was told that it would be compatible. I think you will be OK in the Bahamas
. I was concerned about reception
in the leewards and windwards and they told me that it would be unreliable. By the way, we were just in the DR a few months ago and the corruption was shocking. We were boarded every day and in one place they demanded that we give them 50 USD just to anchor
for one night and had to be gone by 8 AM the next morning.
Read a recent Cruising World article about the DR. I can email
it to you, but would need your email
address. Not sure if I am supposed to ask for that.
