After doing Google and forum searches, I guess I am going to have to throw up the white flag and ask for help. I am wanting to revert the 2.80/2.80 software-firmware to 2.70/2.50. I have found a 2.50 rgn file from forum searches but I am at a loss on how to install.

 

Thanks in advance to anyone who can give an rgn for Dummies lesson.

 

Sorry for double post!

Very quickly: drag the rgn file onto the WebUpdater exe file and follow the steps. When it asks to check for additional firmware updates, just cancel it otherwise you will overwrite the 2.50 GPS firmware you just installed.
