Picture of Garmin GPSmap 60(CSx) Battery Power Fix = More rugged GPS
I have a Garmin GPSmap 60CSx handheld GPS. I have used it while hunting and boating. Lately, the gps has started to shut down itself. It is very annoying when the power goes out when you need the device.

The device works flawlessly when powered though USB-connector or Garmin power connector. Power issues are only when used on batteries. There has to be a problem with how the batteries are connected to the board.

The problem was also more frequent when boating because of the vibration.

Clearly the connection is not rugged enough. So I decided to dissassemble (and reassemble) the device.

Step 1: Remove the back cover

The back cover is held with six screws and glue at the antenna side. It was quite easy to disassemble, only the glue made me think if  I had not found all the screws.

Fixed the problem right away many thanks! A perfectly good gps saved from redundancy because of this fix. Would not have dared or bothered without your article and photos.

You're most welcome. Two years since my fix and still working with no problems.

I used a pencil eraser to clean the contact surfaces and bent the battery compartment contacts so they made firmer contact with the circuit board. So far, so good..

I also thought first that cleaning would be enough. However, the contacts did not seem oxidized, that's why I chose to do bomb-proof fix. My garmin has been OK almost 2 years in boating use. That means being exposed to heat and water.

Simple but effective! (Might be a problem concerning the warranty?)

Yeah, you can forget the warranty. My GPS is 8 years old, so warranty is *not* an issue. This was indeed a simple fix. I made this instructable, because this requires some "courage" to disassemble the GPS. I would have liked if i'd seen how's it done beforehand.
