About This Manual
We at MX Marine have attempted to take care and develop manuals which provide in-depth information. Obviously, we can’t anticipate every configuration in which you might install the MX420, but we can help make your work more thorough and enjoyable.
This manual is organized by first describing the list of included items for the particular model you purchased. The sections that follows detail the technical specifications of the MX420 navigation unit and the MX421 antenna unit. This is followed with the mechanical and electrical wiring diagrams and installation notes to guide you in the installation of your MX420 system.
Should you require additional technical support, please first contact the dealer where you purchased your MX420. Since your dealer sells and installs the MX420 and many other types of equipment, they are often your best resource for technical questions. You can also contact
MX Marine for technical assistance:
