I have a Pioneer DEH-X6910 that I just installed in a 96 Silverado Ext Cab, and everything works fine except I’m not receiving any phone audio through the interior speaker. Music plays just fine over the Bluetooth connection, but upon making or receiving a phone call the caller can hear me just fine but I can’t hear anything they’re saying. I’m on my second one I took my first one back thinking faulty stereo, the second one is doing the exact same thing. All wires are hooked up correctly through a wiring harness. Any help would be greatly appreciated thank you.
Try to check default speaker. For exampleon android you can choose to send call sound to phone speaker. Iphone got same option. Try check settings in bluetooth and phone. Also try to check call settings during call.
