Looking to attach a hard-wired FM modulator for my ipod while I wait for a plug-in solution. Figure it's a compromise while I wait. So....where do I find the antenna wire? Trunk? Head? Some other place?

The modulator goes inline with the antenna. Instructions are generic: unplug antenna from radio, insert wire a to radio, plug antenna into modulator, etcetera.

It wasn't obvious what the boxes are in my trunk. I don't have nav, but there is one horizontal box and one one vertical (sirrus sat. radio.) I also have a 5 disk changer in the glove box. That's it. No NAV.

I need to run the plug for the ipod and a power switch to enable the modulator to the cabin.

Seems like 2 choices to place the modulator: trunk or glove box. I guess it depends where the antenna wire is. I'm pretty adept and educated with electronics, just don't want to mess up panels, etc. on a nearly-new car. Last time I messed with an auto antenna, the coax was about the width of my little finger. I didn't see anything that looked familiar behind the boxes in the trunk.

Thank you!
