I do not know the specs of your Zumo
However, a common error is to copy everything into the root of the SD card
1st there has to be a folder called Garmin on the root of the sd card
ALL other folders are sub folders to it, so:
A map image goes into the Garmin folder
A GPX file goes into a GPX named folder which is IN the Garmin folder
Yiou can have more than one map image in the Garmin folder- just rename them:
being careful not
to change the.img extension -
that is for the GPS to use and not for the 'nut' which connect the handlebars to the bike!!
