I've been using a Zumo 590 for many years and like it a lot. Last year it started not charging the battery for use off the bike, not really a problem but have read it is a common one and not a hard fix. Then the on/off button failed as in it fell out and is gone. I found a stylus tip off an ink pen that worked well when covered with electrical tape. Not pretty but functional. Plus it is kinda skint up in places. Today called Garmin about a possible fix and they said mail it to them and they will replace with a rebuilt 595 for $171 including tax and shipping. Add 11 more for me to ship to them and I have a newer model and perfect unit I hope. Garmin is good to deal with today as they were years ago when I had a problem with an old 550. Kudos! Looking forward to seeing what the 595 does diff over the 590, I heard it includes off road mapping, hopefully more than just that.
