I traded bikes and my GPS was a part of the trade. It was Garmin 2720. I had no problems with the unit. Now I have two bikes, I just want one unit. All the new waterproof units are expencive and I don't know if its really a smart investment. I had an idea, but I don't know if I'm in a right direction : buying used galaxy note 2 off Craiglist ~$220 and a waterproof case ~$30. I then can either buy an app, or download and cache maps from google and use the unit only as GPS. Please let me know your opinions and experiences about it! Thanks!!!
