Zumo 660 Intermittently connects to PC

 

I have Win7 that I have been connecting to regularly with the zumo 660 for the last 11 months. Recently it takes 3 or more attempts before it will connect. The green eject icon shows in the system tray and then disappears and the zumo boots up in normal map mode. I hold the on/off button for 8 seconds and get the soft reboot and usually after 3 attempts or more it will connect.

I have 2 nuvi 765Ts that are not having any problems. I did reinstall the usb drivers for the heck of it with no change.

Any thoughts on what could have happened in to the zumo (before I spend time on Garmin hold)?

Likely culprit?

Have you attempted a hard reset of the zümo? If that doesn't fix the problem then the problem is hardware related, not software. If you're using the same cable for all three devices, then you may have an issue with the mini-USB port on the back of the zümo not working properly. Either the port is worn out through repeated insertions and removals, the port is delaminating from the board, or the traces on the board are corroded.

Hard Reset

Did the Hard Reset with no success, thanks.

I was thinking it was a hardware problem myself but hoping that some obscure fix might surface.

Try using a Q-Tip with a

Try using a Q-Tip with a small amount of rubbing alcohol on the port. It could be that the contacts in the port are dirty and thus not making good contact. That may not fix the problem, but it won't hurt to try it either.

SD Card ???

Seems to be connecting now. This is my 3rd zumo 660 in the last 10 months. All 3 had constant shutdown and reset problems. On the 3rd unit I moved all of the Custom POIs off the SD card to internal mem and I haven't had the first shutdown since. Thats been 3-4 months now. The only thing remaining on the SD card has been some photos from some of my trips, all sized to 480 x 272 screen. I do know that every other time I go to look at the photos they were not visible so the SD card was missing again.

Then I ran across this Garmin FAQ to remove the SD card before performing a Master Reset.

Though it was addressing a different problem, I took the card out performed a master reset and the zumo has connected every time since.

I don't know what the problem with the zumo 660 and its internal SD card hardware is but it looks like I just need to leave it out for now and see if I have any other problems.

In the past I have tried multiple different sd cards in each of the zumos, of different sizes, from different manufacturers, with no success.

I wonder if I should go for zumo #4 before my 1 year is up?
