2720 USB Port Dead - Unseen by computer

So, my trusty 2720 will no longer connect to a computer via USB cable. I have tried multiple cables, wiggled them, and attached other things (camera) to prove that the USB ports & cables are working fine. I also tried a different computer.

I also installed the most recent Garmin USB drivers.

The tech at Garmin had nothing else to try when I called to ask.

I popped the case open and there was nothing obviously wrong visually with the USB port that I could see.

Any thoughts appreciated. I would really hate to buy another unit right now, but if I can't pull my tracks off the unit or load new routes from the computer, it isn't worth much to me.

My 2610 had the same problem a few years ago (I think it's the same basic construction) and I found the usb connector was broken off of the circuit board.

Here is a link to my repair:

The other thing that it could be is the little tabs on the back of the board need to be bent out slightly to contact the main board when re-assembled.

Good luck,
tom

Thanks so much, Tom!

Success!!!

Rexbro, you are The Man! Hope you don't mind, but I took screen caps of your pics and added some circles to clarify what I did.

I opened the unit and pulled the small board that has the USB port attached.

Rather than remove the USB port, I tried a slight variation. I let my soldering iron get nice and hot and then held it against the 3 tabs, one at a time, where the circles are. The idea was to liquefy existing solder and allow it to re-join any cracks that might have developed. I could not see any even with my big magnifier, but thought it worth the effort.



Next I took a close look at the tabs on the bottom of the board that make contact to the main board.

What I found was that one or 2 of my tabs were slightly bent down. No way of knowing if it was far enough to cause contact to be lost, but I took a tiny jeweler's screwdriver and bent them all out so that they were just slightly higher than parallel to the board surface.



I then re-assembled and brought it to the computer, where I proceeded to hook up its power cord and USB cable. No sooner did I power it up than the computer recognized it, and sure enough, when I fired up mapsource, I was able to pull the tracks made during my last trip!

Thank you so much, Rexbro! __________________

Re: USB Repair of 2720

Thank you very much. My USB port wasn't being recognized by MyGarmin, MapSource or Basecamp and I removed the rear over and took a look. I removed the USB board and found the tangs were a little bent. I cleaned the tabs and used a flat blade paring knife blade to re-align the tabs on both the boards and re-assembled the unit. Bingo...the 2720 is now recognized and I'm currently updating my Lifetime maps to the 2014.4 versions. I cannot thank you enough for your help. I have a Nuvi (BMW Nav5 on K1600GTL) and 2 2720 StreetPilots, plus a couple handhelds. I prefer the 2720s and am really thankful for this site and your assistance. The pics were invaluable and the directions were spot on.

For the benefit of anyone new coming across this thread: FWIW, sometimes a failure to recognize unit via USB can be cured with a master reset, so one need not always refresh the physical connections as detailed above. Worth doing a master reset before taking the whole thing apart.
