View Full Version : Adding XM to an 05 STS?

04-18-09, 02:08 AM
Hi guys, long time no posting here. I am looking at an 05 STS tomorrow, non-nav, just the plain radio. It does not have XM, which I really would want.

What does it take to add OEM XM to a car that didn't come with it from the factory?

Many thanks

I think even the plain radio has XM, as I have nevr seen one without it. Get a VIS report and it should show an XM radio ID#. Call XM and give them that #, tell thenm you want to activate it.

Why not just buy the aftermarket add on ? Works as well as a built in unit and very small .
