Hi,
I've downloaded the new Lowrance update for the Touch units, but I can't open the file as instructed on the Lowrance update page.
It specifically instructs not to simply copy the folder, but rather, open the folder and copy all the files to the SD card
Installation Instructions

Unzip or extract the files from the downloaded folder. Copy all file(s) into the route directory of a blank SD card, make sure you are not copying the folder, only the individual file(s) must be copied. Insert the card into the display and switch on, the upgrade should start automatically

Computer says Windows can't open the file and offers to search for an extension that will do it but i'm having no luck with it.

thanks for your help,

Lowrance HDS 9 Touch
