I have a garmin Nuvi 2445. I have recently changed my car. My car is a Kia Picanto. \n\nWhen I plug the sat nav into the car it goes into charging mode. I cannot have the sat nav plugged into the car electric and use it. Of course this is going to make long journeys impossible as the charge on the sat nav is not long.\n\nDoes anybody have any idea why this is happening?
