I got a 2005 Scion tC back in May and promptly installed the empeg the following weekend. All is well except... I'm getting VERY poor AM reception with little to no signal strength based on the meter (yes I'm just noticing this, I only listen to the radio for traffic/news and obviously not very often.) FM stations come in just fine with plenty of signal.

Also, AM stations tuned in just fine using the stock head. I double-checked all the connections and everything seems to be fine. Do Toyota's/Scion's use a signal amplifier or is that ruled out by that fact that FM stations are good?

I'm using an original Tuner that has been with my MK2a since the beginning. The Tuner has worked perfectly (AM and FM) in my last 3 vehicles. Could it be the shorter antenna that scion uses?

Thanks
