Radio Reception
 

Aftermarket headunit fitted, why is the radio reception terrible? The only station Radio 1 is perfect any other and the quality is terrible! Why is that and can it be fixed? Cheers guys

I had a similar problem. There is an aerial amplifier in the car that is powered from the oem head unit. You need to connect a wire from your head unit (think it is the blue wire /remote) to number 14 on the wiring harness. This fixed mine (2004 WRX) .

Does anyone experience this in a 2011 WRX STi? My car has the factory upgraded Pioneer sat nav unit and the radio reception is pretty poor. Is there a similar fix like above?

I have attached mine to the amplifier booster and it did fix matters, in so much as I can now at least receive Radio 2. That's about it though. Certainly none of the RDS functions work. So the booster is either goosed or simply not very good to begin with.

Don't know about the 2011 model but I guess if it's factory upgrade, it will at least be wired correctly.
