5 of 5 Thank you - Great video! January 31, 2021
Reviewer: Louis from Maryland  
Hello NewPower99,

Just wanted to write and express my thanks for your quick service.

I’m still shocked at how quick I got my replacement battery for my Garmin GPS. Ordered it on Thursday…it arrives on Saturday….Garmin has a new battery one hour later!

I was considering trashing my old Garmin Nuvi 660 as I had it for over 14 years and it finally died. My parents bought it for me as a Christmas gift. It was rather expensive back then…around $700.
Since both of my parents have passed away the Garmin has some sentimental value as it helped me many time to navigate some long road trips.

Thanks for the step by step video on how to change the battery….I never would have figured out how to get inside of that Garmin…it wasn’t hard but you just have to take your time and watch the video.

Again my thanks!!!

Best wishes,

5 of 5 Great Battery June 28, 2014
Reviewer: David Allen from Pulaski, NY United States  
I recommend you read all the reviews many pointers. I did the process in a room with a light colored tile floor. Spring and holder flew out twice and it made it easy to find them. I used a small pointed awl to remove the spring. Screws are in VERY TIGHT. Screen ribbon came out of connection. It is a little work to reconnect, but can be done. One Philips screw would not come out and I stripped the head. Used a small blade jeweler's screw driver to remove it. Couldn't get it back in.
It took me about 1 1/2 hrs. I paused at each step and the screen froze up and I had to re-start the site and watch the video to the point I was at. I also studied each step closely.
Reassembly, turned on Garmin and every thing worked. I charge it for 5 hrs. With full charge I turned on the unit and left it on for 1 hr. Stayed on and the battery indicator still showed full charge.

If a 71+ year old can do this anyone can. Don't buy new get this battery.

4 of 5 Worked as promised April 23, 2013
Reviewer: Richard KM from Newark, CA United States  
Hi received  this in timely manner (shipped out same day)  - package came with tools and battery, no instruction, however the video on the website or Youtube is all you need.

Some tricky parts in opening the case ,
1) when trying to slide the spring cover to remove the receiver antenna - not sure how much force I could apply and the cover did not have a notch to get a grip on.
2) opening the cover I used a very thin blade flat head screwdriver to get it started. Then the tool worked fine.
3) would have been nice to have some double sided tape to hold the new battery down. (so minus a star)
4) re-assembling / reseating the pcb was tricky, make sure the battery is flat and in position before pushing. The pcb will need to go in at an angle (left side first) to allow it to reseat the connectors  (audio , usb etc) before pushing it home.

Overall, very satisfied after a charge looks like all is well with my Nuvi 660 again.
Thank you

4 of 5 Almost as good as new June 19, 2012
Reviewer: Anonymous Person from Warrenton, VA United States  
I am very pleased with the battery overall.  I just finished the install process and while it is as described, it is now quite as easy as it appears.  It was more difficult to remove most items than described, but to be fair it was an accurate and very complete description of the process.  As noted by another individual, the spring assembly did take some time to get loose.  Also, most of the screws were quite tightly seated, my main worry was stripping them.  But, at the end I got them all out and all is well, with the exception of the two screws under the GPS swing unit.  Frankly, it was pretty tightly held together and I was more worried about stripping the screws putting them in and having them be raised, so I kept them but didn't reinstall them.  So be it.  I also had trouble getting the two circuit board screws back in flush.  I ended up putting two pieces of electrical tape to avoid the screws touching the circuitry.  All in all the described 15 minutes took me 1 1/2 hour,
