I cant tell the difference between these two other than name and pricing. Any pros pro's out there that can tell me?

Thanks!

 

Your getting a 1 way remote start system with the dei phone app system. If you use this system. I would add a different gps tracking system with it. Both units are the same. This way you can use the phone app to start the car. And the gps system for security.

 

like the DSM250?

 

Buy a viper 5901, Buy the smart start without gps, Use a gps company like mobile iq for gps services. I not really into the dei gps at this time. It does not out perform my mobile iq unit at this time. Make sure you are using a dei 520t back up battery on the alarm system too.
