I'm considering adding a remote start system to the car for the upcoming winter. Since I don't want to be carrying around a second key fob and the standard fob can't be reprogrammed to work with a basic remote starter I've starting looking at the mobile remote start systems that use a smartphone and app. The two that are in contention are the Mazda Mobile Start and the Viper Smartstart. Apparently the Viper system is coming out with an updated app soon. The MMS is about $450 where as the viper smart start module is about $150 but that doesn't include an actual remote starter so tack on about another $100 buck or so for that. I think it still comes out cheaper then the MMS system. On feature that I like with the viper system it that is says it will work with the iphone and siri. You can just tell Siri to start your can and she does! I don't know if the MMS system has that feature. It'd be nice to not half to always open the app. Does anyone have any experience with the viper smartstart system? How do you like it?
