Telematic Smart-phone controllers add the ability to control remote starting, keyless-entry and GPS tracking all from your Smart-Phone. The modern Telematic Smart-Phone controllers plug directly to the remote starter or bypass module with a single cable. This is a very easy upgrade when combined with the correct remote start kit. The MyCar telematic Smart-Phone controller is a universal Smart-Phone controller designed to be compatible with FORTIN, Idatalink, DEI and CRIMESTOPPER. Do not let the word "Universal" imply that it does not fit exactly but will work. The install is a simple plug in with one cable no matter the brand you are paring with the MyCar. I have the MyCar Smart-Phone controller installed and paired with the CRIMESTOPPER SP-502 Two-Way remote start - alarm combo. The MyCar has performed flawlessly and has been very useful every day. No worries about being locked out of your own vehicle and having the ability of checking the vehicle locks, voltage and location is worth $29 bucks annually. One locksmith visit alone will cost $100 or more and not to mention the horror watching as the locksmith springs your window frame with a wedge.
