We purchased Version 4.2 inDecember and have been a bit slow learning to use it. Out flash card came with map files dated May of 2007. I went to MySendero dot com for the first time today with the hope of downloading current maps. I find that the available maps are in files dated May 2007. It was my understanding that the maps are updated annually. Are the 2007 maps the current maps, or have I missed a link? Thank you for any response. and
