Extension Harness AX-Series Interface - Fits GM 2016-2021

You have found that your GM vehicle is going to be utilizing one of our AX-series radio replacement interfaces, but there is also an AXEXH series extension harness that may be required. GM has a tendency to have the tuner located remotely, such as the rear of the vehicle or passenger kick panel, so Axxess offers a solution to extend your AX-series radio replacement harnessing coming from your radio to reach it. If you have narrowed down what radio replacement product that fits your GM vehicle in our Axxess Vehicle Fit Guide, it will also let you know if you need one of these extension harnesses. You don’t want to be left “short handed”.
