My husband has a Pioneer aftermarket head unit installed in his truck. It’s older still has the removable face plate. For his birthday I bought him an upgraded pioneer. Was told that since he already has an aftermarket radio installed and has the module thing for the steering wheel controls and it was pioneer to pioneer it would be a simple unplug, swap, plug and go. Well that all went easy auntie he tried to listen. It has power to it shows on the screen it’s playing but no sound. Watched some videos, tried the “fixes” and no luck still no sound. Any advice? Attached photo of old radio installed and a internet photo of new radio. Thanks
