Found some good stuff on the net and thought I'd share the info for anyone having the same or similar problem.
My battery in my Garmin Nu vi 760 Chit the bed after 2 years of use. Garmin wanted $60 plus dollars to fix it with a 3-5 day turn around,I really cant afford the down time since I need & depend on it for work purposes,so I did a search and found the battery for $6.99 and $4.49 for shipping!
Then I did a You tube search for "how to" and found a 12 YO replacing the battery in all of a 6 minute video,he prolly could have done it quicker but his chubby little fingahs got caught up a couple of times
So not bad $12 bucks for the battery and 6 minutes down time VS $60 bucks and 3-5 days.
