My GPS 295, which has worked wonderfully for years, suddenly won't aquire SAT signals. It powers up normally, goes in the acquisition mode, and never shows a sign on any signals. Later offers the SIMULATION MODE, which works good. Have peeked inside and see nothing out of order that could have such an effect.

Re: Garmin GPSMAP 295 won't acquire SAT signals
If the GPS has not been used and allowed to acquire satellites within the last three weeks then follow these steps:
1. Plug the GPS into a wall outlet with the unit on and allow it to charge for eight hours
2. Perform a satellite reset: Start with the GPS off, a good antenna, and a clear view of the sky. Press and hold the ‘Out’ button then turn the GPS on using the ‘Power’ button. Continue to hold the ‘Out’ button until the “I Agree” message appears on the GPS. Release the ‘Out’ button and allow the GPS to acquire satellites for at least 15 minutes.
If the GPS is used on a regular basis but continues to show the incorrect date and time after power on then follow these steps:
1. Update the operating software to the latest version through www.garmin.com
2. Plug the GPS into a wall outlet with the unit on and allow it to charge for eight hours
3. Perform a reset: Start with the GPS off, a good antenna, and a clear view of the sky. Press and hold the ‘Quit’ button then turn the GPS on using the ‘Power’ button. Continue to hold the ‘Quit’ button until you see a message on the screen about deleting user information. (If you have not backed up the user information and want to do so you will need to download this information prior to completing this reset as the reset will delete user information.) Release the ‘Quit’ button and highlight the “Yes” and press the ‘Enter’ button.

Check that the date shown on the unit is correct. If not, choose autolocate and allow about 10 minutes for the unit to find satellites. If this works, then the internal lithium ion battery is defective.
Hello there and happy new year
If Your Unit Cannot Acquire Satellite Signals
For your Garmin GPS unit to acquire the satellite signals it needs to function properly, the unit must be taken outside, away from mountains, tall buildings
and heavy foliage where it can get a clear view of the sky. Keep the
unit stationary for several minutes while the GPS unit acquires the
necessary satellite signals.It may take several minutes for the unit to locate a good solid signal
Hope this is very helpful please keep me posted on this ok? Best regards Michael
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.
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
Detailed road map data, with addresses, hotels, gas stations, etc. can
be loaded into a data-card/cartridge/memory-card using Garmin's
Mapsource software such as Metroguide or City Navigator. This can
be changed as needed via a PC. The 295 does not have driving routing/guidance through the streets as most of today's GPSs have, but it will show you exactly where you are on the street (but it should be switched to Road mode). Driving routing is possible on the PC using Mapsource, but ithe route doesn't transfer well to the 295 because of the limits on waypoints.
