Hello from a newbie on this site. Am replacing an older Garmin with a new etrex20xt. My question is which map, Topo24k or Hunt view gives more detail to USFS roads ? I will be using this in Michigan running mainly Forest Service numbered roads, which there are many. Will also use this for hunting. Hunt view is intriguing as it gives topo plus birds eye views. Any help will be appreciated. Thank You-Lou
