    I have exactly the same problem and have taken the following steps to address the problem to no avail.

    1. Changed USB Lead

    2. Reinstalled the software and drivers

    3. Disabled Fire wall

    4. Installed on a different computer.

    Given the steps Ive taken I can only conclude its the unit itself and its "handshake" with the software.

    I am having problems downloading info from my Garmin Forerunner 305 too. I keep getting the message "As this is the first time you are using the Garmin Training Centre you need to connect your deivce...." The device is connected and recognised by the PC.

    I have tried downloading the latest software. Removing and reinstalling software and drivers.

    I have downloaded and installed Sportracks Software and this has allowed me to import some, but not all of the data on my Garmin.

    Same problem. The computer says that there is a problem with the connection, but the watch reads "transfer complete." This is a deal-killer for me. I've cleaned the contacts, re-installed the software and updated from the website. Any other suggestions are more than welcome.

    YES! I also had the HTC sw installed recently and from memory the garmin stopped working approximately when I installed the HTC software, there is a program entitled internet-pass-through that could be the sinner. When I uninstalled HTC software, the garmin 305 was once again able to connect to my win7 32bit pc as it used to. Shame on probably HTC for distributing such software. Anyway, the HTC "iTunes copy" type of software was just a joke of low quality.

    I would like to approach HTC with a warning on this disaster that is almost impossible to detect. Send me a facebook message if you encounter this problem. Thanks.




Had identical problem (incredibly frustrating, glad I didn't have the heart rate monitor attached !) I did the following to resolve the issue :-

. Uninstalled the GTC
. Reinstalled it from the supplied disk
. Updated the Forerunner with the latest v2.8 software and GPS v3.00 from the Garmin website.
. Updated the Garmin USB drivers
. Updated the GTC with the :-
Training Center For Windows software version 3.3.2 as of November 7, 2007
Forerunner 305 - greycornerrightcccccc.gif

This was on the Garmin site :-

Still early days, however the PC and forerunner are at least talking to each other :-)

Can't find satillittes

Yes, resetting the Forerunner 305 would be just like resetting the Edge 305. If you are still unable to locate satellites with the Forerunner 305, please go to the following page on the Forerunner 305 Main Menu > Settings > General > About Forerunner and reply with your software version and GPS version.

I have bought a new computer, windows 7. I cannot install driver for forerunner 305.

Glad to HELP YOU!

It's a well-known issue between Windows 7 and Garmin Forerunner.
Garmin company says it's a compatibility issue concerning the USB connection between the computer and the device and usually they recommend to be an Intel Chipset.
Try to download and install using the latest drivers available on their site on WIN 7 and Forerunner 305.m You have them ALL here and the USB driver was released this year and it's the last one on that list.

Garmin 305 stops uploading data

Try maybe a different computer and see if it works. If it doesn't then something is wrong with your item. Clearing the history won't help.

Can't upload workouts from Forerunner 305

After deleting all but one month of history on the device, it still would not upload new workouts. It would hang in garmin connect, or indicate problem in training center. The solution, finally, was to delete all history EXCEPT for the new unloaded workouts from the device. They then uploaded.

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.
