Got a factory remote start? That's great... until you're out of range. 👀

Many newer vehicles come with remote start, but that doesn't always mean you're getting the range, convenience, or security features you're looking for.

We've been getting more calls lately about vehicle break-ins and theft concerns. A remote start and security system combo can give you added peace of mind with features designed to help protect your vehicle while making those cold mornings a lot more comfortable.

Plus, if you've ever wished you could start your vehicle from farther away, there are options available that go beyond what most factory systems offer.

Stop by Mobile FX on Cambell St. in Rapid City or call 605-716-0770 to learn more about remote start and security options for your vehicle.

The chilly mornings and fog are starting to roll in, and winter isn't far behind.

You don't have to start your day in a freezing vehicle. Our customers love their remote starts, especially the convenience of starting their vehicle right from the app.

Still craning your neck every time you back up? 👀

How much distance do you really need to stop? 👀

Most drivers underestimate how much road it takes to react and come to a complete stop. At 70 MPH, your total stopping distance can be nearly 315 feet, or about 24 car lengths.

As we head into fall, shorter days, foggy mornings, and changing weather conditions can make visibility even more important.

If your headlights seem dim, yellow, or don't give you the visibility they used to, it may be time for an upgrade.

We install lighting upgrades, auxiliary lighting, backup cameras, dash cams, and other visibility-focused upgrades designed to help you see more of the road ahead.

Here we are installing Stinger RoadKill sound damping material 👇

RoadKill helps reduce panel vibration and rattles, enhances mid-bass and subwoofer performance, minimizes backwave distortion, and cuts down on unwanted road noise. The result? A cleaner, more solid sound system that lets your audio perform the way it was meant to.

Thanks for trusting Mobile FX 🔊

Need a better view when hooking up to a gooseneck or fifth-wheel trailer? 👇

A third brake light camera gives you a clear view behind your truck and into the bed, making trailer hookups easier and helping you keep an eye on your cargo while you're on the road.
Clean install. Better visibility. More confidence backing up!
