Hello, The option lowercase has a side effect on lines name. To draw oriented text along lines features, Garmin use a vectorial uppercase font. With the lower-case option, some GPS like Etrex cannot display these names or you can see almost for example "G**** R****" horizontally instead of "Green River" along the corresponding river. It would be great if the lower-case option could be managed with a third state : partial-lower-case whic preserve upper case for lines and allow lower case for points and polygons. A fast patch could be something like that in polylines class (probably in the 2 write methods) : memoLabelUpperCaseState = label.upperCase; label.upperCase = true; do everything needed for writing polyline ; label.upperCase = memoLabelUpperCaseState; All the best, David
