I have a 2010 Elantra GLS with the PA710S radio (Has XM). I have a Pioneer AVIC-U310BT that I will be replacing the stock radio with. Since my commute in the morning is long, I have fell in love with XM but I want to avoid running another ugly looking antenna for it. Since I have the XM antenna on the roof and its already where I need it to be, is it possible to buy an adapter so I could connect it to my Pioneer XM box? I pretty sure is all I would need is an adapter but I was wondering if anybody was familiar with this or has any pictures of the stock XM connection. Thanks all.
