I have had the 350LM for sometime but never tried to build routes. I have made a few now and tried an off road one over the weekend. It showed my route as a line with no other detail, such as other roads? This might not be the best unit for me as I want to use it mostly for off road and riding in Baja. Not sure if I should look at the Montana 650 and sell this unit or am I missing something on building my route? I have spent hours reading on the subject and am completely confused.... HELP!!!
