    Works  great when used with the cigar lighter adapter, but won't turn on when batteries are inserted. Have also used 12V auto source to the battery terminals inside the unit battery compartment, and the unit still does not work, so it is somewhere beyond the battery compartment.

I have discovered an intermittent problem on my 10 year old 295 when powered by batteries.
It appears that the chrome plating is de-laminating from the battery contacts that are either side of the back panel attachment hole. At first glance it looks perfect but if you run a fingernail or other small item across the face of the contact you will see and hear a movement as if there a a loose layer of foil over it. This is causing all manner of faults including 'external power lost, shut-down in 30 seconds' when the external power was not even connected at all!

Batteries leaked. Will not operate. Who can repair?


I also have one that will not turn on, with either internal or external power. Would you be interested in selling the unit? Maybe between the two us, I could get one of them working?

My device has seemed to have lost its ability to acquire satellites. Any suggestions? It's Garmin GPSmap 60CSx. Thanks.


I would try a reset and firmware update first. To Reset the unit hold the Page and Enter keys down while you power up the unit. hold them down until you get a prompt asking you if you really want to reset.

Garmin has a free software called webupdater. this will put the latest software in your unit. If there is a GPS chipset software available please apply that also. It will be in the list when you run webupdater.

You may want to try an external antenna also to see if an internal connection came loose.

My garmin 545 wont turn on. it was working fine and I switched batteries. now it wont turn on


Follow these directions to replace the system software of your Garmin GPSMAP 545s. This should fix it up. It is not uncommon for firmware to become corrupt when switching batteries on some devices.

  1. Click on "Download" and choose to save the file to your computer.
  2. Choose a location where you can easily find the file, such as the 'My Documents' folder or 'C:\'.
  3. Once the download is complete, go to the location where you saved the file.
  4. Double-click on the downloaded file. This will automatically extract the files to C:\Garmin and run a program to transfer the software update to an SD card.
  5. Load the SD card into your GPSMAP 545s and turn it on to replace the system software of your unit.
I hope that helps.

Will not run for more than a few moments off battery power


Watch out for that - if you use regular batteries, they probably won't like that. They're not designed for recharging. The GPSMap 295 can batteries and external power at the same time because it has circuitry that switches between the two - power is not being sent through the batteries.

This guy - http://www.fixya.com/support/t2487552-garmin_gpsmap_295_will_not_run_from - opened his up and found a loose screw. I have the same problem with mine which I'm about to try. This may help you as well.

Garmin gpsmap 295 will not run from internal battery power


I had the same problem. Reluctantly, I removed the batteries and the 8 phillips screws from the the case back perimeter. Be careful on opening. The unit is designed to open from the top and hinge at he bottom to keep the ribbon cables from being stressed. The unit should open nicely and lie flat on the table with the two bottom halves butted against each other. Get a magnifier and ensure the printed circuit board attached to the bottom half has all 3 screws. (I found one missing that has 2 functions - securing the board and delivering battery power. Mine had wedged against a piece of clear plastic...it was hard to find!!!) I carefully removed the wedged screw and returned to the circuit board left most attach point. Close up the unit and we were back in GPS heaven. Battery power restored!!!! and my $250.00 still in my pocket. Yipppeee.

GPSmap 60Csx power up problems


I had the problem where I ended up disassembling the Garmin and adding a small piece of plastic to the on/off button. For some reason the push button on the top does not reach the one on the circuit board.
