So once the install was complete, I fired it up, and tuned in some stations I knew to broadcast HD radio (my wife's car has HD radio from the factory). Well to my disappointment, probably 1/3 of the stations broadcasting in HD were picked up in their digital form with my new radio.
I sent Pioneer a letter regarding the issue and got this response:
Thank you for contacting Pioneer Electronics (USA) Inc.Now, when I installed the radio, I did leave the aux turn on (blue wire from the radio) disconnected from the power antenna wire (on the wiring harness adapter) because I don't have a power antenna - think antenna that extends and retracts. But this letter has me wondering if there is an antenna booster that the aux turn on wire may trigger. Do any of you have any knowledge of an antenna booster in our trucks, 2012 specifically?
Please check the installation of your unit.
Make sure the unit is grounded directly to the vehicles metal chassis.
Some vehicles have built in antenna boosters. When you replace the factory, you need to make sure the booster is still being activated. On our radio you would normally use the blue/white wire to trigger the antenna booster.
