CARLISLE COUNTY, Ky. — Crews at a local construction company were sent home this morning, after discovering fire destroyed one of their main trucks overnight. The owner determined the fire didn't start outside the truck or in even in the engine like you might expect but on the dashboard and was possibly caused by an explosion in the GPS.

An insurance agent will help determine that tomorrow but for now, the truck owner is just happy no one died or was hurt by the explosion.

Trendon Burnett believes a battery could have caused the explosion inside his truck.

"The dash is totally melted, the visor, ceiling, everything melted and burnt. We all know hard a windshields supposed to be and you can tell by looking from outside, it actually blew it outward," Burnett explained.

Burnett is the owner of West Kentucky Garage Builders and admits he leaves the Garmins plugged in on all his company trucks because never imagined anything like this could happen.

"I've done a little bit of research and I've never heard of nothing like this," Burnett said.

But mechanic Mike Boyd actually isn't surprised.

"Batteries on your car are hot all the time," Boyd said. "They carry 12 volt, 12 volt system on most vehicles and if something shorts out, yes it will cause a fire."

He said sometimes it's the car battery itself. Other times, it's the gadgets on the inside.

"I've seen that damage before now whether it was from a GPS or something I have no idea," Boyd said.

Boyd said typically, car chargers actually have a fuse inside. That's supposed to prevent shorts and fires but Boyd said that doesn't always work.

"If it doesn't blow a protected circuit or fuse, then you're going to have a fire in your car," Boyd said.

The fire ruined a truck and is damaging Burnett's business.

"It really will hinder us. We had a job this morning and in the morning but we'll just have to completely shut down that ground team," Burnett said.

An insurance agent is coming out to asses the damage Thursday. Burnett said he's got to get a replacement truck as soon as possible because now he's behind on jobs.

He also called Garmin and so did Local 6. A company spokesman released this statement:

"Garmin takes this matter seriously and is looking into the alleged incident. We look forward to discussing the matter with Mr. Burnett."

The mechanic said the key is to unplug everything all the time. This also applies to stuff like laptops and home electronics.

We also checked with the U.S. Consumer Product Safety Commission and found no word on the Garmin.
