I installed the Avic D3 awhile ago and just got the xm/nav. I have a 2004 Chevy Silverado that came from the GM factory XM ready with the XM Antenna mounted to the roof. I want to use this antenna with my Avic D3 and XM but I cant figure out how. So for the time being I just used the antenna that came with PIONEER GEX-P10XMT. Is there a way to use my factory mounted antenna. I called XM and they said yes but i cant figure it out. I hope someone is able to help me out
Current Setup:
Pioneer Avic-D3
Pioneer GEX-P10XMT
Here's a picture to show the antenna I am talking about:
