Sirius or XM option.

Before purchasing my Ford Escape Limited I had XM in my previous vehicle. I went with XM because my Wife has a car that came with XM built in, so we now get a multi radio discount. After purchasing my Escape I was bothered by the fact that Sirius XM does not offer a multi radio discount if one radio is on Sirius and one radio is on XM even though they are the same company. So I am now forced to use a aftermarket SAT unit so I can have XM in my Escape.
It would be nice to have the option for either an XM tuner or a Sirius tuner when you purchase your vehicle. it would be nice to have the option.
