That is what the shop did, because they wanted too much money to replace antenna. I picked up car this am, drove to work, parked in garage, car would not start at end of day. I have a power pack in trunk for just such situations. Double checked the unplugging of the antenna, by the time I got home, no turn signal, no brake lights, etc. car is on the charger now. I guess I will see in the am.
