I have recently purchased a 530, after my Etrex 30x developed a screen fault. It has taken a long time to learn how to use it. Mostly, because it comes with all the bells and whistles switched on, and I have to work out what screen has just popped up, and where the setting is to stop it popping up again. It is obviously a very clever piece of kit with far more features than I am ever going to use. So far, I have been quite happy. I have been particularly impressed with 'Climb Pro' which I certainly did not expect. I grind up hills extremely slowly, and thought 'Climb Pro' would only be useful to those for whom an AAA rating is an attraction and not a warning, but I actually find it helps a lot! I have not, so far, been amazed at the battery life, but maybe I just haven't found the right setting yet. My biggest complaint is that the bluetooth connection to my iphone7 is unreliable at best, meaning that the Live Track and Incident Detection features are a bit hit and miss. I also find the Garmin App really confusing. It took me a long time to work out how to plan a route on the app. It is not obvious, and you have to go down several dead ends before finding the correct menu option.
