Hi all, i purchase my zumo xt in 2019, which was fine to begin with, however roll on 18 months & it would loose power/connection to battery!

I replaced charging leads & bought a new mount! However unit still turning itself off when on the move.

Garmin eventually replaced unit with a recycled one & its still doing same, however this unit barely fits in mount & with no secure ‘click’ when locking in. When i eventually managed to get it to stay in the holder, the unit kept turning itself off as before!

Contacted garmin AGAIN & im having to replace leads & mount again! How many times have i got to do this to get a unit to work ergh!!

Any advice gratefully received regarding next steps!

Can we assume that you have the power lead secured in the mount with the tiny screw - quite a few people don't?

Are you using the very latest lead as per this picture?

Yup looks exactly the same!

& secured with timy screw!

I also have a charging issue when connected to mount, it goes straight to battery mode. If I connect via USB it charges. The mount is wired to an ignition live connector and the 3rd pin on the mount is showing 5.14v when ignition on. I went into the diagnostic screen (see below) and see that when plugged in to a USB it says it's connected to the garmin mount which it wasn't it was my PC and shows that there is no USB cable detected. When connected to the mount it shows no connection whatsoever and uses battery. The only thing I've not been able to do is try it in another mount.

I managed to try a friends mount, however his XT also flicks from charging from battery & turning itself off!

There is obviously a fundamental problem here that Garmin are refusing to acknowledge for a £400 SatNav, this is not acceptable!

Anyone from Garmin here????

Returned satnav under warranty but the replacement does extactly the same. However when I plugged it into the dedicated output for my fog lights it shows it's charging. Output from both plugs is 12v with 5.14v at the mount pin. It's got me puzzled.

I'm a little confused. How did you plug it into a fog light output? Do you mean you used the 12v plug and USB connection, as you would in a car?

Another desperate guess on my part: when you tested for 5.14v at the pin on the bike mount, what ground (earth) reference were you using? A part of the bike, or the other pin in the mount? If the former, it's possible the bike mount harness is not properly grounded. I know this is a long shot, but just trying to help if possible.

The fog light has a dedicated socket I replaced it by plugging in the Garmin lead and mount. When I press the fog light switch it turns the satnav on and device powers up and shows its charging. If I put a multimeter on the mount connections it shows a 5.14v output. The positive being the 3rd pin the 1st being negative. Both the fog light socket and the auxiliary socket both give the same readings. So you would think with either socket being used the satnav would be charged.

Just for your own sanity to check it out, why not run it straight to the battery via the Garmin M/C lead.
