what unit do you have? I only know how to revert back to the previous version on the 93sv echomap plus units. I would save the update to a folder on your computer so that way if you ever needed or want to revert back its on your PC. It's really easy, just click on Download and then click on the up arrow and click on "save as", then put it in the folder you want on your PC.
