Need Aftermarket alarm for 2013 gt
So I have a 2013 gt with only the reverse sensing and security package and I'm not to into the alarm so I've decided to look into an aftermarket one. I've been looking at viper since that is what I have on my old car. I went to best buy and found the viper 5901 alarm but best buy says the car is too new to have something compatible especially since I already have an alarm they would need some key thing to put in the car. To be honest I'm a little confused. I didn't think the 2013 was different from the 2012 when it came to that. Is best buy wrong? I only have a month to get an alarm before I leave for college in a new area to me would really like some good protection.
