Where is the FM Radio tuner located?

[pungo]

I want to connect HD radio tuner to the Intravee II interface. I have successfully connected the Alpine HD tuner and used a spare temporary antenna. It all worked great through the NAV screen. I want to Y into the factory AM/FM radio antenna. I found a spare antenna connector in the trunk, but it was a female connector and after connecting to it, I did not get any signal. It must be an input.

I have a 2007 coupe w/ NAV, Carver subs, and DSP stereo system. I guess it's top system offered for this car. Where is the actual FM tuner located? Is the FM tuner in the dash where the head unit is. Is that where the antenna terminates? There are 2 large electronic boxes in the trunk just behind the seats. One of them has several coax connectors with cables on it. Maybe it's the GPS receiver? It would be nice if I could "Y" into the FM antenna in the trunk since that is where I'm mounting the HD radio tuner. Any help would be greatly appreciated.

Hi,

I can't answer all o your questions but:

1. The GPS receiver is behind the dashboard.
2. the two electronic boxes in the rear bulk head will be either/or: Nav dvd (easy to work out!), DSP amp(black metal), Bluetooth module(black metal), TV module (silver metal).

I think therefore that the FM receiver is in the headunit radio in the dash.

Rgds.
