Rather than shelling out $160, call Charlet Moser to see if they will replace the one that is missing.
I lost my Garmin 60CSx a week ago up Ice House...if someone find it..., anyway, I called Garmin because they were sending me and another unit to the replace the unit I lost, a semi-long story. They only charge me $110 rather than the $210 that was already on the books.
I have found the outdoor industry is pretty damn good in these matters.
