I feel your pain, just purchased a new garmin and the magnetic mounting system is good every now and then you can hit that bump and it happened to me just Saturday. $200 garmin road surfing, screen cracked but it still works. I think the solution for this unit is just to glue it to the base with superglue and forget about it. when you want to remove, remove the unit the mounting suction cup and the wire all in one, at least the garmin will be safe and sound. LOL I've been looking for some type of strap myself or a tether that was not allow it to fall to the ground by dangle if it did pop off.
