Zumo 660 not always powering down after losing external power

[SEllis]

Hi,

For some reason my Zumo 660 has just started to fail to show the screen that says that it has lost external power and to choose whether to stay on or turn off.

If I manually turn off, when I come back, the device is flat and has to charge for a period on the cradle before powering on.

Any tips?

Do you ever apply a very fine wipe of silicone grease/lube to the contacts?

I haven’t done.

What power source on what bike?

Wired in with a motorcycle mount to a switched power piggybacking from the 12v socket (that I don’t really use) on a Suzuki 650 V-Strom 2022. It all seemed to start after a time zone update from Garmin. I’ve tried reinstalling the updates using the updater, but no luck.
