Thread: Garmin TransAlpine v4 PRO

Hi, This is my first post on gpspower and there seem to be some great resources and tools here. I am trying to use Garmin TransAlpine v4 PRO on an iMac. I downloaded the 4 (locked) .rar files, unzipped them into a single file (with its separate scq file) and then dragged the gimgunlock icon and the single Garmin file into Terminal before hitting enter. Terminal seems to complete the operation by "writing to file".

My first question is where this file has been written to. Has it just overwritten the locked file in the same folder?

I then connect the GPSMap 62s to the computer, drag the .img file to the Garmin folder on microSD card and open Basecamp 4.2.4.The .img file appears on the microSD, Basecamp appears to be opening it by reading it, but it then disappears from the list of maps on the microSD card.

Please can you tell me what I am doing wrong. Many thanks.
