First, be sure you are outside, in the open when making this diagnosis. Some cars have metallic defrosting layers, which blocks the GPS signal. Also, first fix when new may take several minutes (5-10 minutes).
If, when outside in clear view, you still have problems, try this...
Have you tried a hardware RESET? The button is hidden behind the front panel, which snaps off by a fingernail slot located directly under the GARMIN logo on the front panel.
* Use caution removing and reinstalling the front panel... it's somewhat fragile... wiggle it a little to get it off.
Press where it says "Press to Reset", hold for a second or two. Charge the unit with the car cord or USB cable, then try to turn it on again.
Once you can get the unit to (hopefully) turn ON, you should run all updates (there may be several!) using Garmin's
Webupdater. (Connect to computer with USB cable first.)
Hope this helps!!
My Garmin C340 worked fine for about one year and then it started saying "Acquiring Satellite" showing the wrong location where I am located. When I first turn on the unit it shows a Map Updater Notice. I have heard that sometimes if you update the map then this fixes the problem of not acquiring a satellite. Is this true or is the unit broken and I would be wasting $70.00 purchasing an updated version of the map.
Thank you.
The unit is trying to locate satellites but can't even when not in motion with clear view of skies. It shows the wrong location which was the location when the problem occurred. It can try to locate satellites even for one hour but never does. It happened after one year that the unit was working fine. I am not sure if updating the maps which cost $70.00 would help. It cost $120.00 to buy a new one on E Bay.
