Solid display, easy installation

The adhesive mounting template makes installation very easy. However, the template adheres almost too well. We recommend cutting it to size before applying it. Displaying measured values over time is very helpful (gusts, SOG, depth, etc.), but the display only supports three graphs simultaneously.

Nice screen

Our introduction to NMEA 2k. Makes a very high quality impression. We particularly like the flat structure.
Only the configuration of the display is a bit cumbersome.

Good product but pitfalls in implementation

The product appears to be of good quality and starts up when connected to the NMEA2000 network. The current parameters are found on the default pages. On the other hand the documentation is insufficient and to display certain parameters, there are undocumented constraints and it is necessary to call the support (in English in the USA) to know them. These limitations are a little annoying but not prohibitive for the use of the display.
