If your vehicle has Digital Signal Processing (DSP), the purchase of a DICE DSP kit may be necessary.
To see if your vehicle has DSP look for a bare metal coax cable and a 3-pin connector. If you don't find a coax cable and find a
6-pin connector along with a 3-pin connector, your vehicle doesn't need this DSP kit.
