3.5 Aux to XM

[BuildMurray]

I just ordered the Bluestar for my 2011 Silverado. My stock receiver has an Aux 3.5 jack on the front but I am looking for a way to avoid any wires exposed on the dash. I have seen other vehicles that have an adapter that connects to the XM receiver and leaves a 3.5 jack that I could theoretically connect to the Bluestar for A2dp. I am having trouble locating any information for my specific vehicle though and was curious if anyone else has tried something similar. I have posted a link for a corvette using an application similar to what I am looking for. I don't subscribe to XM so I am not worried about losing that functionality. I have seen plenty of helpful posts in this forum and I am looking forward to any info/suggestions you all might have. Thanks in advance!
