Garmin Forerunner 305 won't charge

I have a Forerunner 305 for a few months now. Recently, it wouldn't charge and I believe it is the contact point issue.

These units seem to be suffering from a bad connection on the inside of the unit. My wife's did the same thing. There was a connection inside that wasn't making contact. First try cleaning the 4 brass connection tabs on the watch and check your charger to make sure the tabs are raised and not squished. Second try to reset the unit. Hit mode reset and power buttons all at the same time. Hold these for 3 seconds and then release. If these do not work here is what I did. There are no screws holding the unit together. I used a exacto blade to very carefully pry the unit apart along the side seam. It's not easy to do. Be very cautious and gentle. Work the thickness of the blade into the joint to gently wedge apart. You are not trying to remove material! Once apart you will see some fingers that make a connection between the upper and lower part of the unit. This is where the problem was with my wife's 305. I gently raised these tabs to make a better connection, It's been working ever since. I didn't try it before but try pressing very hard on the unit where it says Forerunner 305. The case is very hard so it might not work. But if it powers up when pushing you found your problem. Hope this helps. Here is a link I found on opening a 205 (Same process) http://ctorunner.googlepages.com/dismantleforerunner205 To put the unit back together use Automotive silicon/gasket maker. Use a tooth pick to put a VERY small amount of silicon around the entire seam. Put the two half's together and wrap tightly with electrical tape. Test the unit immediately to see if it powers on and off. If it does not open it back up and raise the small prongs that make the connection from the bottom half to the top half. If any silicon squishes out the sides wipe with water and a rag. Let the unit sit over night. In the morning remove the tape.

You can soft reset or hard reset the device. Hard reset deletes all data.

Missing training data from my Garmin 305....


Unless you created a "back up file" with the Training Center software unfortunatly you will not be able to retrieve the data.

Regular back ups will insure you do not lose information in the future.

To back up your data in the Training Center go to "File" and "Back up" I believe the early version of the Training Center did not have the Back up feature so you would then need to use the "File" Export" option.

My Garmin forerunner 305 recently got immersed in


I have read in some other posts about the unit only working while being plugged into a USB port. My guess is that the battery is in fact shot and the unit will only run off the USB port while plugged in. Submersing in water is not a good idea. On the back of the unit there are some small holes for the speaker. These speakers corrode from sweat and eventually quit.

Forerunner 305 won't charge


Question: My Edge or Forerunner 205/305 won't power on. Is there a soft reset that I can do?
-----------------------------------------------------------------------------------------------------------------------------------------
From the Garmin web site.
--------------------------------------------------------------------------------------------------------------------------------------------- Answer: If a Forerunner or Edge 205/305 is unable to power on, a soft reset can be performed to un-freeze it. This will not erase any user data and is most effective if the device is connected to the computer while performing the reset.
To reset the Forerunner or Edge 205/305:
  1. Connect the device to the computer using the USB cable
  2. Press and hold the mode and reset (lap) buttons together for 10 seconds
  3. Release and wait for 3 seconds
  4. There should be some indication of battery charging (either Finished or In Process)
  5. Power the device on while keeping it connected to the computer
In addition, please make sure that the device has the latest software version

There is a hidden recessed button on the right side of the Garmin. Press this button and it should reset the unit and it should turn on immediately.

Garmin Forerunner 305 usb cable won't be read


The problem is probably not with the USB cable if the GPS wont even turn on. The older firmware of the Forerunner 205 and 305 have a problem with locking up. This causes the Forerunner to look completely dead. There is a reset procedure: push the mode and reset button at the same time and then let go and hit the power on button. If it powers on that is the problem. Go to the Garmin site and load the newest rev. of firmware into the Forerunner. Fixed mine and a few friends with the same problem.

I do however have a cable problem. Sometimes my PC will come up with unrecognized USB device and my 305 wont talk to the PC, it does charge. It is the cable or dock for sure, because I have tried a different cable/dock and the 305 has no problem. This is the reason I ended up here. I hope the lock fix works for those with the above problem.
