Standard Horizon CP390i Review

The Standard Horizon CP390i is built around a very high resolution 7-inch display screen that packs 800 by 480 pixels of resolution. Compared to its smaller brother, the CP390i is a big step up in screen space, pixel count, and the ability to see fine detail.

This Standard Horizon chartplotter package also includes a built-in 50-channel GPS sensor, six multifunction soft keys, an extensive package of preloaded cartography and the ability to display video input.

The preloaded charts in the Standard Horizon 390i GPS chartplotter provide detailed coastal coverage of the U.S. including Alaska, Hawaii, and the Great Lakes. It also includes charts for coastal Canada, the northern tier of South America, Mexico, Cuba, Central America, and the Caribbean. This is obviously a solid cartography coverage area that will suit the needs of most boaters. Should you need chart coverage for any other areas you would simply have to purchase and insert the appropriate C-Map NT+ or MAX card in the unit’s single front panel card slot.

The compact Standard Horizon CP390i display unit measures 10-inches wide by 5.7-inches high and 3.9-inches deep. It is supplied with a plastic tilt and swivel bracket mounting bracket as well as flush mounting hardware. A quick reference guide will get you started using this machine right away. More in-depth explanations of controls and functions are printed in the included owner’s manual.

Connectivity

All electrical connections to the CP390i are made on the case back. You will find four twist-lock connectors here, one for power and accessories, one for an optional external GPS antenna, one for a video input and second accessory cable.

If you decide to flush mount the CP390i be aware that you could suffer a potential loss of signal to the internal GPS sensor depending your installation specifics. You may need to add an external antenna in some applications.

With its four inputs and five outputs for NMEA0183 data the CP190i will interface with lots of additional gear. Some of the items that will interface include Si-Tex MDS-series radar, AIS receiver, FF520 black box fishfinder, VHF radio, autopilot and video camera.
