Radio Volume Fluctuating????
Hi... I just installed a new aftermarket Pioneer Head unit and speakers in my Daughters 2009 Cobalt. I installed it using the PAC C2R-GM11 harness and a Scosche CRAB antenna adapter.
Everything went well and works, but when using the Radio while driving the sound volume is going higher and lower. I'm guessing it is a reception issue. Reason being the issue is not there when listening to Bluetooth or USB input music. Only with the radio.
I double checked the Antenna connection and all seems to be connected correctly.
Does anyone have any suggestions?
Also the car did have On Star and XM. My next step is to just install an aftermarket antenna unless someone here has a better suggestion.
