I have to insert one of the unused speaker pins into that position and give it a try. I'll have to leave the factory deck on, but I can set it to 0 volume so as to make no noise. I'll probably isolate it with a relay if this RAP signal is present.

If I could post the .pdf you could take a look.

BTW the 2008 is different than the 2007 Express...

that would be nice if you could post the .pdf. I have a feeling that the bcm is what actually sends the data signal. the deck decods for it self and the antenna is different. The amplifed systems(bose) are also class 2 data and cannot be triggered with a relay. I hope you get lucky though!
