Customer Review: Does NOT work with eTrex Legend Hcx
I was under the impression (it may have been Amazon’s fault) that it would work with my Legend. The replacement back does not fit since the Legend takes micro SD cards. Luckily, I also have a windshield mount that fits into the bracket so I will keep it.
Customer Review: Worthless for the Vista HCx
This product DOES NOT FIT the eTrex Vista HCx handheld GPS at all. Do not be fooled into thinking that it will fit just because both Amazon and Garmin say it will. The Vista HCx is wider than other eTrex units and simply will not work with this product.
