Hello - I am about to remove my stock RNS-E head unit this weekend and install a Pioneer 8200-NEX Navigation/XM radio. I ordered the adapters I need from Enfig and was curious if anyone has experience re-wiring the stock Sirius antenna. Is there a wiring diagram or schematic which the wires run? I'm also curious if the aftermarket antenna might be better located or located more out of sight. Please let me know if anyone has any experience with this. Thanks!
