Hi Josh,
I live in Pensacola, FL and have a question for you. I just took a trip to Texas and while there my siren went off and the lights blinked. Sometimes the lights do not flash though. When it goes off it just keeps going. Nothing will turn it off; not even cranking the car. Have you guys had a lot of problems with this? I went on the mercedes forum and a few people said that it was the SKREEM (alarm). They said it has a battery in it and when the battery dies then it will go off. I wanted to know if the dealership you work at has had experience with this.
