new to forum...first post...own a 2009 VW Jetta which came with factory installed SERIUS...changed to an after market radio which has XM/GPS.. with antenns mounted on the dash....was not able to use the factory roof mounted satillite/GPS anntenna...is there a factory looking GPS/XM antenna I can purchase or does anyone have any other thoughts or ideas?...thanks...

I bet if your handy with a soldering iron and got the right connector you could make the factory antenna work.
