Solutions for adding XM Radio to a vehicle factory radio system?

Aftermarket receiver is probably your best bet... there's a few that have adapt-o-matics that let you use the steering wheel controls.

Don't look past the Sirius Stiletto 100. Basically a TIVO for radio (pause, rewind, record, etc). Have 100 hours of free music from it. Plus you can undock it and go mobile sat radio.

Anyone know if XM/Sirius officially merged? Noticed a bunch o' new channels lately.

Yes they merged a few months ago........

Some Sirius channels went away, some XM went away, got rid of duplication

the stock xm reciever is behind the glovebox and just plugs into the stock radio.

Check tssradio.com for the units, i know they have sirius replacements for the stock xm, they might have xm units too.

I'm changing mine to sirius, i have an '07 Chev p/u, and will have no use for the xm reciever when done, all you would need is the antenna. You can have mine for the shipping when i change it out and its on a free trial right now.

The xm satelite is low in the southern sky of the US, so any time your on the north side of a mtn you loose reception, specially up here in Canada. Sirius has geo sync satelites so not so bad.
