Overview
Not a remote starter on its own, the Viper SmartStart Pro module adds GPS tracking and smartphone control to a Viper system. It mounts out of sight under the dash and reports location, speed, movement and battery alerts to your phone.
Location sharing and smartphone control from anywhere with cell service turn an existing Viper system into a connected car setup. Alerts need a Viper SmartStart Service Plan, and remote start depends on a compatible Viper system installed alongside it.
Who it's for
Drivers with a Viper remote start or alarm who want to find, monitor and start the car from a phone. Owners without a Viper system, or who want no service plan, should look at a self-contained starter.
Pros and cons
- Phone control from anywhere with service
- Hidden under-dash install
- Geo-fence and speed alerts
- Location sharing and history
- Service plan required for alerts
- Needs a Viper system for remote start
- Install wiring not listed
Performance notes
Tracking and alerts ride on the module's own GPS and cellular link, so coverage depends on cell signal where the car is parked. Remote start, lock and unlock pass through the paired Viper system, which handles the vehicle side.
