We don't have the experience here of all the worldly issues with Raymarine, Just on what we have seen which is limited.

I suggest all with a Raymarine to sign up and follow this thread to keep up with the latest on the Units and feel free to bring a thread over here to inform others.

Just sign in and don't forget to register your units for the extra year warranty and email updates for the units. Its a Win Win for all.

Cheers!!!
