Review on Enhance Your Garmin GPSMAP Experience with the iSaddle CH-152-159 Windshield Suction Cup Mount Holder by Eric Chapman

If the description says the item will fit your Garmin eTrex GPS then it should fit without the modifications made by other reviewers. I was hoping for an efficient, reliable, tethered GPS mount for my kayak. What I have is a mount that is so far out of spec that it can't be used. The width of the rail on this device is 21.16 mm, the width of the receiver on the GPS device is 27.68 mm, not even close (photo). I have not skimmed it, sent it back.
