Can I combine Sirius and XM Sub?

[bobvick]

Hello,

I have a standalone Sirius radio unit in a 1999 Honda that I use to commute to work in. I also have a 2006 Dodge Charger that has a Sirius radio in it. I recently purhased a new Honda Accord that has XM in it. I was wondering if I can combine the subscription in all of the cars together?
I do not drive the Dodge that much, so it may be cheaper to disconnect the Sirius in it and buy a cheap XM for the commuter Honda.

Your help will be appriecaited.

Thanks

If it helps, I have a lifetime Sirius sub for a OEM radio on a car I traded in on a Toyota (which is XM ready). I e-mailed Sirius and asked if I could transfer that lifetime Sirius to an XM radio. They said while they've merged their systems are still standalone and they can't combine two services at this time.
