I installed my Garmin today and tapped power from the map light. I used the power from the top wire that operates the light continuously, not the dimming wire. I tested the GPS and it worked. Buttoned things up and then, no map light and no power to GPS. Took it all apart again, verified connections. Nothing loose or out of place. The trunk vanity light quit too. Only the dimming part of the map light works when the key is turned off. Help. I couldn't have blown a fuse, or the map light would have quit altogether, right? Please help; I leave on my trip in four days. You can't imagine my frustration after working on this all day!
