Start-up loop For some reason whenever I turn the unit on the main screen that says streetpilot comes on then the saftey warning not to use it while driving then when you click ok it goes back to streetpilot 2620 and keeps making the same circle. Is there any way to reset the unit. I know by holding down certain buttons while turning the unit on you get different screens is there any way of making it read and display maps again

Reset use a soft reboot. Or hard reset make sure you back up all your settings on fish finder with chip or home computer. OK guys so the first thing you wanna do when resetting your unit whether it's soft reset or hard reset we're gonna start with a soft reset which is gonna save any GPS data anything like that so we're gonna head over hold the Power & Page button press the power button we're going to go over and press power button but I'm at the unit but up until you see the warning screen where you have to except the depth on reset Can see we still have our Saved waypoints. OK now I'm gonna show you how to do a hard reset again turn the unit off you should always use the power key never just flip the main power switch to off then press and hold the plus minus key as well as the power key let go of the power key keep holding plus minus until the warning screen comes up in a hard reset your going to delete all data on this year it's gonna be like we just bought it went to the store and bought it and cam home with know data whatsoever no settings nothing OK I warning screen has came up we can let go of her buttons and press except start demo. OK now I'm gonna show you how to do a hard reset again turn the unit off you should always use the power key never just flip the main power so that our unit is off then press and hold the plus & minus key as well as the power key don't let go with the power key holder plus minus until the warning screen comes up and a hard reset is going to delete all data on this year it's gonna be like-you just bought it went to the store and bought it and brought it home no data whatsoever no settings nothing OK or warning screen has came up we can let go over buttons and press except start demo now. OK so now you should not see any saved data so that's how you do a hard reset and a self reset. Load your Data card and shut off the power key. Then turn back on and follow screen steps. This should fix you issues.

1. Step 1 Calibrate the screen of the Garmin StreetPilot C340. If the touch screen does not seem to respond when you hit it with your finger or a stylus, you may need to calibrate it. To do this, turn the unit off and then hold down the "Power" key for approximately one minute. You will see a calibration screen come up that will recalibrate the GPS unit.
   
2. Step 2 Reset the Garmin StreetPilot C340. If your GPS unit is not responding or is stuck on a particular screen, it may need to be reset in order to operate. To reset, remove the face plate of the unit by gently prying it off. Locate the "Reset" button under the face plate and press down in order to restart the device.
   
3. Step 3 Change the fuse of the Garmin StreetPilot C340. If the fuse blows on the GPS, you will need to make a replacement using an ACG/3AG 2 amp fuse. Unscrew the adapter cord at the end and remove the fuse found there. Put in the new fuse to see if this returns function to the unit.
   
4. Step 4 Update the software for your Garmin StreetPilot C340. If the GPS is not providing you with correct directional information, you may need to update the software or download new maps onto the device. Connect the Garmin StreetPilot C340 with the USB cord to your PC and log on the Garmin website for available updates.
   

You are caught in a loop most likely caused by a failed microdrive. Search Garmin 2620 cornice for a thread that is likely to provide the information about the failure you are experiencing. In short, if it is the Cornice drive that has failed you will find it very difficult to repair, if not impossible depending on your level of expertise and ability to find a used part for repair as the drives needed are no longer manufactured or readily available.

Safety mode (prevents you from changing routes whilst in motion) is enabled disabled in the system options.

Found by navigating Setup (spanner at bottom of main screen) --> System --> Safe mode

Connect it to a PC and delete the map(s) using windows explorer.

Most likely your hard drive is gone bad. Push "menu+find" buttons then turn on, you will get diagnostic screen, it will show if your cornice drive is bad. It will say"Cornice Dive removed"

I would like to know the same thing! My father has the same unit and he updated his with version 4.80 & web updater (both free) on garmin and it solved his problem. I believe my problem is that my North America v8 did not install properly. ????? well see

Hold down Menu-Find buttons if you get this screen, your hard drive gone bad. Garmin charges $275 to replace your unit
