Re: Hunting GPS map sd cards
In the second half of 2010 we began adding detailed National Forest Roads and Trails with names and numbers. I'm surprised you're not finding what you are looking for, because most people think we have too much data on our maps. This leads me to think you have an older version. Which product do you have and what version is it? Is it our NW region Washington, Oregon, and Idaho map?
Don't forget you can always try our free trial on the computer and see if the road data you need is there, and you can always send your chip back for a refund.
