Overview
Cold driveways and hot office parking lots are where this Compustar system earns its place, starting the engine from a long distance so the cabin warms or cools first. The two-way remote confirms commands, and both remotes also lock and unlock the doors.
Two-way confirmation at long range lets you start the car from an office or apartment without guessing. Installation is the real hurdle: a bypass module and professional fitting are needed in most vehicles.
Who it's for
Commuters in harsh climates with automatic cars get a warm or cool cabin and confirmation from far away. Manual transmission owners and anyone planning a quick self-install should look elsewhere.
Pros and cons
- Long listed range
- Two-way remote confirms commands
- Spare one-way remote included
- Safe for diesel engines
- Automatic transmissions only
- Bypass module sold separately
- Professional install recommended
- Phone control needs a subscription
Performance notes
Range depends on obstacles between remote and car, with buildings and walls cutting it well below the open-air maximum. The two-way remote reports back so you know the command landed. Start reliability depends on a correct install with the right bypass module for the vehicle.
