I just upgraded my head unit from the JVC-NT1 to the Pioneer AVH-P8400BH and I'm loving every minute if it. I was just wanting to know if there is any way to utilize the stock XM radio antenna that came with my truck, or do I need to get an entirely new setup like the manual of the Pioneer says? It says I need to have the Pioneer GEX-P920XM XM Satellite Tuner for it to work. Here is where I would get it http://www.amazon.com/gp/aw/d/B0009I...dir_mdp_mobile.
If I do have to use it, could the antenna that is already on the roof of my truck work with the Pioneer tuner?
