Hello does anyone have a solution to solve underneath mentioned problem?
I would like to use my eTrex Touch 35 with City Navigator NTU 2017.1, Topo Germany V7 Pro and Topo Austria V4 Pro.
These maps are unlocked, checked with PGFT 18.104.22.168 x64, and they do work onto Oregon 650, Oregon 550 and Dakota 20 and did also work onto this eTrex Touch 35 device with a patched firmware version 3.00. At the the original eTrexTouch25_35_Webupdater__320.gcd I applied the procedure as described into this thread (tried it two times).
But the maps are still not shown into the map choice menu onto the device. Also the warning "Cannot authenticate maps...." comes up at Power up.
I would like to read any helpfully message, Thanks.
