In the above example, the second set of “w”s is too long to fit on the line, so the final “w” wraps over to the next line since there’s a maximum of 4 lines of “Description” text, the final set of 17 “w”s doesn’t show up. If there is no available “next display line”, the additional text characters will be truncated on the GPS display. If a single line of text exceeds the total display length, it will wrap the remaining characters over to the next display line by themselves. Here’s a POI display for a dataset where the “Description” data has one set of 48 “i”s in a row, one set of 16 “w”s in a row, and then two sets of 17 “w”s in a row. For capital letters, the corresponding numbers are 29 “I”s on a single line, but only 18 “W”s. For the widest small letter, “w”, only 16 of those will fit on a single. Different characters take up different widths on the display, and so the number of characters that will fit on a single line will depend on the total width of the set of characters.įor example, you can fit 48 of the letter “i”, the thinnest small letter on a Garmin, onto a single display line of text in a POI data screen. That’s not really correct the Garmin GPS unit will display characters until they fill up a display line of text, and then wrap them around to the next line if they exceed it. Some websites state that the maximum name length is 44 characters in total, and the maximum description length is 88 characters. : The newer Colorado/Oregon/Dakota GPS units can store and display more data see this Oregon Wiki page for more information. Description (optional): Text, 1-4 lines, typically 20-25 characters per line (theoretical maximum of 48 per line).

This post will show how to create a POI datafile that can be uploaded into a Garmin GPSr.Įach POI can have up to four different sets of data: In the first post of this series, I compared the features of custom POIs (Points Of Interest) and waypoints for a Garmin handheld GPS unit (like my 60Cx).
