Ok Murph, I'll bite. I found this product:
http://store.xmfanstore.com/audiovox-fm-direct-adapter-xmfm1.htmlThe Audiovox XMFM1.
Will this still require the 2 gm antenna adapters you speak of? I've never uninstalled this head unit before (my girlfriend's) but I've done my own and plenty of friends' head unit installs before. I was just trying to avoid getting too invasive in her car.
By the way, the $11 dollar FM mod from radio shack didn't quite make the cut. It did work (Inno2 unit with Inno1 car kit), but the quality was horrible.
