With USB ports now commonplace in new cars, trucks and SUVs, it didn't take long for engineers to realize more is better. The 2014 GMC Sierra SLT 1500 and Chevrolet Silverado LTZ 1500 we recently tested each had five USB inputs for charging cellphones, music players, tablets, cameras, toy helicopters or whatever else has a battery and USB charging capabilities. The base trucks have two USB ports each.
The trucks' USB locations are divvied into a group of three ports below the climate controls, and the remaining two are in the center console. Not only are there five inputs, but a Chevrolet representative says all five can read devices as well as charge them. Often extra USB ports are merely charging docks and aren't capable of reading a device for music.
