When replacing your head unit don't forget you have to get power to the factory antenna amplifier.

Do you happen to know which factory wire that would be?
The "Radio Upgrades" is where I remember reading something about it but that thread is pretty big now.
Thanks in advance.
So I also have the jbl synthesis, however I think the previous owners had xm hooked up, I'm wondering now if they maybe used the antenna amp as their power source.
I upgraded my HU to a Pioneer and used it with only one antenna plugged in for a couple of weeks. The signal strength was not great and I experienced some loss of signal in lower lying areas. I couldn't pick up any AM stations at all.
I bought the two into one adapter and tore everything apart and installed it. The signal strength improved only a little bit and still don't have really any AM station coverage. The HD channels come in pretty clear most of the time but when the signal is weak, it bounces to analog sound and won't display the artist and song info, album art, etc.
My HU is a Pioneer AVH-X3800BHS.
Interesting as I'm looking at the pioneer Abu-x2800bs, ... This isn't looking good.

Pretty much describes my pioneer unit except the adapter bringing the two antennas together made mine worse.
