Alpine Ezi-Dab-Bt
I have had the device for more than a year and have hardly had any problems with it. Now, all of a sudden, the message came up that I should check the power to the antenna. How should I do that exactly? The unit no longer works at all. Is this because I unscrewed the antenna from the car for a short time? But it still worked during that time.
