Review title: Topo maps very poor; no upgrades
Product review: Great idea to have topo and roads on the same unit, but topo maps are 90 meter (so topo lines about every 300 feet of elevation) and other map features such as streams are missing. I couldn't find a way to get any map upgrades--an FAQ on their website says none are available, although the instruction manual claims you can use programmed SD cards for upgrades (and even shows pictures of how much better the upgraded maps look on the unit). That's pretty deceptive. I bought this to replace my old sportrak pro, which has great downloadable maps and navagation features, but is slow and has a poor screen. This unit might be great for driving, but don't buy this if you also intend to use it in a serious way for outdoors or hiking. I'm returning mine today.
