I had this exact problem. I deactivated the flight plan that was still in the system from my last flight & the problem went away.

My Garmin MAP 295 won't power up. Third time in 5 years.


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!

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.

Can't find any satellites


If you don't use it very often it can take time to find its location. Have you tried using the 'set initial location' option? Once it knows roughly where it is and what time it is it can then work out which satellites it should be looking for instead of searching for any/all of them. The manual does say that it will take time if it has no initial clue as to where on the planet it is, and if you're on the move while it's trying to work that out then it may take even longer. Obviously, if it has a poor view of the sky, or if most of the satellites are behind you and you have a tin roofed aircraft then that will probably not help either.
How do you know the antenna is OK?
Do you have the remote antenna to try?

No lighting


Your unit has lighting, it's just that it's set so low that you can barely see it (or not at all in bright sunlight). If it wasn't working at all then you wouldn't be able to see anything.
When the unit is on, press the power/lighting button (the red one) briefly and repeat. You will see it cycle through the highest, lowest, and user pre-sets. Stop on any of those and use the arrow up/down key to choose your own level. Press enter when finished. You can do this even when the unit appears black in bright sunlight.

GPS GARMIN 340 turn it off by itself.


Does the unit comes on by itself once power is applied to the unit? If it doesn't come on by itself, then there is a problem with your power supply. The unit is designed to detect when an external power supply is applied and turn itself on. It is also designed design to detect if you unplug the unit from the external power supply. It will say "Lost external power, shutting down in 30 seconds". BTW are using Garmin cables?

Garmin c340 gps freezes up


Avoid buying Garmin GPS. Their units have a non user replaceable battery that last about 2 years. After that, you have to send the unit to Garmin to replace the battery and be hit with at least $150 plus shipping. Possibly more if they need to fine tune something else. Look at other brands with easier battery replacement such as Sony, Navigon, etc. Garmin is a total rip off.
