Charging a Garmin Nuvi GPS & hearing voice prompts
I purchased a Garmin Nuvi GPS unit for use in the car and on my LT. The unit came with a cigarette lighter socket type charger. The charger works fine in my car.To see if it would work on the bike I purchased a lighter socket from the local automotive spares shop and connected it directly to the terminals on the battery and plugged the unit in. No joy. The little light on the back of the charger socket does not go on the the Nuvi will not charge. I tested the terminals on the socket and have 12.5 volts.Why will the charger not work on the bike and should I use the standard power socket on the LT and make up an adapter with a "cigarette lighter" type socket on the one end for the GPS unit? Can I somehow connect the earphone out socket on the GPS unit into the radio on the bike so I can hear the voice prompts from the navigation system?
