We recently bought a used car and wondered what this antenna looking thing that was mounted on windshield was? My daughter somehow determined that it was an antenna for a remote starter. We were never told from seller of car that it had a remote starter, we had no remote or didn't even know if the system was even installed. We took to Finish Line and was told they would have to drop the dash board just to see if the system was installed. Finish line looked at car and was able to determine which starter it was. They had a remote in stock, were able to recode system and now we have a viper remote starter for my daughters car! The only cost we had was for the remote and a little for labor. I was very happy that they took the time to research system and make it work. All this took 2 hours and was a fraction of the cost of a new system. The starter works great and my daughter is going to love having a warm car from now on! Thanks for the great service! Would definitely come back to Finish Line next time we want a remote starter for our cars.
