I have lost the miniscule magnet that sits in the battery door of the Zumo 660, not the first time either, but this time its definitely lost.
I have tried magnetising things of the same diameter then cutting to size, but no luck.
Has anyone else done this and found a solution?
I am in the process of contacting Garmin, to see if they do spares, but will need a bush mechanics fix up in the meantime.
