Better then pods

Reviewed By Sam O (KNOXVILLE, TN) Reviewed for a 2008 GMC Sierra —9/13/2017 5:13 PM

Up to 9 gauges at once and easy to use. Best part is you can check your check engine lights and clear the codes. And has a good maintenance reminder on all a wide variety of maintenance for your truck. The only thing I am not sure about is unplugging and replugging it in if it saves your data.
