I have a 60CSx and now I can not imagine living without it. I use it almost every week to auto route for business and it never misses a beat. Gets me to the right location and gives me alternates when traffic or other issues arise in front of me on the road. I bought it for deer hunting public land and it works flawlessly. I have gone in to stand locations and mark them under heavy canopy and can come back 6 months later and get right back to the same tree over a mile in the woods. The tracks you can laydown with the unit will allow you to walk within 6 to 10 feet of your original path. I can not say anything bad about the unit. I have the City Nav v8, with a scandisk 1 gig chip. I do not have the topo software since I feel it will do me no benefit. It has been with me in 90 degree weather to -10 degrees no issues and have tested the water tolorance and no issues. I would totally recommend it to anyone. ~Jeff
