Question about Garmin Forerunner 305 GPS Receiver
When I plug my 305 into the computer, it opens the window for Training Center, and then a message appears: There was a problem while communicating with your device. Please make sure it is connected to the computer, then try again.
It just started this after 15 months without a problem. I also sometimes get this message: The remote could not be resolved or something to that effect. Thanks.
I am new to the Garmin Edge 305, and started getting this problem yesterday. Indeed, yesterday it was the first time that I downloaded Courses.
I followed the Guest solution, deleted all new courses from my Garmin, and it now WORKs!!!!
Uploading my courses back again to the Garmin made the problem return back. I need some more work to identify the bad course.

It definetely seems to be a Course issue with the 305. My battery completely drained, and upon trying to plug it into the Training Center, it would charge but would not sync. I deleted a few of my more recent courses on the watch without luck. I deleted a few more; still with no luck. I finally deleted them all, not really expecting it to work, but it did! I didn't lose any runs and my courses are still on the training center, which I could push back onto my watch (although I am not sure if I will, if it causes me to run into this problem again).
Simple solution: On your watch, go to Training / Courses / then proceed to delete each course. Once they are ALL deleted, plug your watch back in and click Receive from device button...it should work.

I just had the same problem. The problem is definitely with the courses. My problem started after I sent a workout from TC to the watch. My solution was just to delete all of the "courses" from the watch, not from TC. Once the courses were deleted from the watch, I could send data from the watch to TC again without a problem. I'm using a forerunner 305.
Also if you keep backups of your computer, just close TC then restore the directory "C:\Documents and Settings\All Users\Application Data\garmin\Training Center". That will restore all of your history to TC. This is for WinXP, other OS's are probably similar.

The issue for me was with my USB port in the computer. Some usb ports, especially those on the front of computers (and all on laptops), will will go into a powersaver mode. When they go into this preservation mode, they can still charge the Garmin, but it has issues with transmitting data (evidently more energy intensive). The usb ports can be reached through your Control Panel, and you can elect not to have the port go in to efficient mode (google for specific instructions).
Since I made this correction, I haven't had a single problem.

I have bought my Garmin Forerunner 305 and done my first run tonight with it. I was really impressed and made a course from my run. All backed up fine. I then made a second course from it and backed up and it got the COMMUNICATON ERROR as other have had.
I installed the S/W on another computer and it still failed.
I removed all courses from S/W and watch and it worked again, then I just made one course and it still works.
Try it - might work for you too!

If you import courses from TC to the 305 edge or forerunner it will not transfer to TC the next time you try. You can transfer the files to other programs without a problem. Apparently the problem is with TC not the device. To fix this delete your routes and you should be able to transfer the history with out a problem. I don't understand the problem, but this worked for me.

I had this problem intermittently with my Garmin 305 for several months. I found out the cause the hard way. After buying a new 305, I took my old cradle to work so I would have one at home and at the office. When I tried to synch my new device at the office, I got the error message. My fix: Peel the pad of the back of the cradle. Remove 3 screws and take the two cradle halves apart. Remove small circuit board with the USB connector. Use a pencil eraser to burnish the gold pads on the circuit board. Also burnish the gold connectors on the top half of the cradle that mate to the gold pads. Re-assemble. Now it works good as new. Also, make sure to wipe off your sweaty device before putting it on the cradle, so that sweat does not make its way to the contacts and cause corrosion.

I deleted, manually all workouts and all history off the watch. Then I used the garmin webupdater program to erase the latest update off the watch and reinstall it. So far it appears to be working. I'll post back in a few days with an update.
yeah it bites that i lost about 1/2 a month of training data and I have to re type in my training programs, but if this fixes the problem, I will be VERY happy!

I have had the same issue now with my second 305. I returned my first thinking it was a defective system and reordered another one. I used it about 3 runs and got the error again. I got really upset (because the watch is great when it works). I deleted all the routes on the Training Center and the watch of courses I ran. I uploaded my latest data from the watch and the error no longer appeared and then I just sent the old routes back to the watch. Problem solved. Hope it works for you too.

I was having a similar problem. Training Center would autolaunch when the 305 was plugged in, but it would not autodownload, and trying to download would give the "Device not plugged in" error. The device did show up Windows Device Manager.
What I found is that the Garmin USB driver does not like VirtualBox talking to it at the same time as GTC. When I quit my VirtualBox window and reconnected the watch, GTC came up and downloaded like normal.
So make sure you shut down VirtualBox/Vmware, etc. before trying to download.

I have two 305's, so I have two charging cradles. One would not import, but when I plugged the second one in, it did...after installing the drivers automatically. Not sure what the deal is, but it seems to have something to do with the drivers. I am using Windows 7. I had used the other dock for a couple of years...so this was a surprise.
I had used the other cradle several times, but I noticed this time it was not auto-launching the Training Center when docking. I cleaned the contacts with an eraser and that did not help, either.
Make sure you try to reboot if you are seeing issues. Also try unplugging the dock and plugging it in to a different USB plug.

This solution worked! Thanks! I was using the front USB port and have not had a problem until today. As a quick workaround, I used the rear USB port and aside from getting a notification on Windows that a new device was being installed, it transferred the data as usual.
