I have bought Garmin zumo 660 on local market without battery. I want to check is this device fault, but I don't have battery or a car holder or a motorcycle holder.
When I connect zumo with USB port on computer I see logo Garmin and message "Insert battery".
Does anybody know how to connect some other battery with 3,7 V on zumo? I don't see any marks on zumo 660 or battery pictures that can help me.
Original battery costs about 55E, but I don't want to buy it until I check that zumo works.
It has 4 pins and doesn't look like Garmin nuvi batteries.
