MUST READ - Device works great but in my opinion Garmin sucks at explaining how to use it. I mistakenly thought I would turn it on and start getting great cards right away. Not correct. You need to download Basecamp, go to the map, mark the area you want to detail and then upload it to Garmin. You will only receive high-resolution maps in the areas you have selected. It's all free and included. In retrospect, it is clear that the amount of data would be too large to have high-resolution maps for the entire USA. All you have to do is tell Garmin which areas you want to use in high resolution. I don't understand why Garmin can't state this in the instructions, on the website or on the support pages. You may have read it right away, but it took me a lot of headaches to get to this point. I like it now.
