Zumo User Forums

My zumo XT, when using the motorcycle mount and battery fully charged, will cycle through "connected / not connected" every few seconds.
Anyone else experience this?
I am guessing when the battery is fully charged is draws very little or no charging current so the device thinks it is not connected. Then, a small current is drawn and the unit thinks it is connected again. Only a guess.
If so, bad charging design!

This is not normal and have never had this happen with any of my Zumo's. Have you tried cleaning the contacts?

Yes, I've covered all the obvious checks, different charging sources, connectors etc. it is a behaviour of the fully charged zumoXT.

Well it should've do that. Mine is always on the powered mount.

Garmin has produced an "improved" cable. AFAIK, they replace the old ones at no charge. There is a discussion here that includes a picture that helped me identify whether I had the old or the new one. I had the old which had been trouble free however I called Garmin and they readily sent me the new one.
Also, there are discussions here that contain tips about adding a spacer behind the cable pin assembly in the mount (I used a piece of foam weather stripping). This adds pressure to the back of the pin plate helping insure the pins stay in contact with the XT. There is a picture of the foam trick here somewhere too. I will be back with the URLs to those discussions if I can find them.

All of that said, if your XT is new than none of the above should apply and contacting Garmin is probably the best thing to do.

Edit: This discussion shows both the old and new cable as well as the foam trick.

Thanks for the info. Yes, I have the new mount as shown in your photo.
However, the problem lies within the zumoXT charging circuit sensing.

Thanks Peobody.
After reading your post and looking at 'Rofar's post about reinforcing the back of the mount connector I tried that and - so far so good.
It seems it was the lack of sufficient pressure on the 5V pin contacts on the motorcycle mount.
And, I have the 'new connector' that was suppose to fix the problem---try harder Garmin!

This happened to me this fall. I did two things:

- cleaned the mating surfaces with a pencil eraser, and
- used a dab of dielectric grease on the pins and worked them in & out.

those 2 pins on that rubber charging plate are on springs? what about a squit of WD40 degreaser on the pins to unstick them?
