1734C Waypoint Size



Is there a way to increase waypoint size on the 1734C CMAP? According to the manual, the waypoint size can be increased if Navionics card is used but it cannot if a CMAP is used. This appears to be an indirect way of saying waypoint size cannot be increased without any map card.

Is there a "tech" method (i.e. from a tech settings screen) to do this?

Is there a Furuno software update?

There is no software or “tech trick” to change the size of the waypoints on the 1734C/NT.
There have been software updates issued over the years and you can check these on our website. Once you have the product page of the 1734C/NT displayed click on the software tab and open the software history document. Depending on your current software version you may or may not want to upgrade.
