I have a Garmin Oregon 450 and bought a Micro Sd map card. The card location is really bad design as it sits under the batteries and within 3 months as I was changing the batteries the Sd card slipped out of position and broke as I was installing the new batteries. I contacted Garmin, they would not replace the card, so now I am forced to buy another... Grrrr. Has anyone else have this problem? Is there any other solutions?
