Updating a garmin nuvi

I don't know if the battery level had anything to do with it.Third, For G7TOWIN Under the File tab -- "configuration", you enter a configuration page.

Also my (nuvi 255) kept all my saved addresses when i selected no when "there was a box that came up about continuing the update and erasing user data" after everything had successfully installed! Thanks again, saved me 0 i dont have right now as i need this for work. I hope you registered it with them way back when you bought it.There's a check box for "com port." Make sure the USB box is checked and hit the "save" button.Then under the GPS tab -- "Get GPS ID" -- I got an error message.I cannot get it to start up, and I cannot get my computer to recognise it. I have not tried a hard reset of course as I'm trying to save my data.(My unit has no button on the bottom but I know how to access the YES/NO screen.) Since I had just gotten a new one you'd think I'd be okay with that except I had wanted to transfer over some saved coordinates that have no address (such as the ones I use when I go camping each year).
