I am on my 4th unit now since may 18. all with the same problem. the last one was out of the 3 month warranty, that Garmin give for refurb units. I had a long game of email tennis stating units not fit, supposed high end units, not fit, all I am going receive from you is a refurbished unit that no doubt had the very same problem that I am complaining about blah blah blah. in the end they agreed to send me a refurbed unit, as a goodwill gesture, alas still with only 90 day warranty. Every thing about it is the same, apps, pages etc etc, however, to me the screen seems clearer (although nothing to compare it to) the digits, words, maps all seem sharper, bit like going from normal def to high def, and another thing I noticed, it connected to my computer (Mac)and Garmin express, a lot quicker, to plan a route with basecamp. I am one month in so have to wait and see. if this fails it will probably be my last one. revert to soggy maps in tank bags.
