I just bought a 2005 Magnum RT with a factory installed nav/satellite radio. Of course, there is no manual so I'll need to go buy one.

Can someone tell me how to retrieve the ESN from the radio so I can activate it with Sirius?

Thanks.

Call Sirius, they'll tell you how to find it. I believe, though, the esn can be found on channel one.

I just found the answer elsewhere. With the key in ACC and the radio off, press and hold EJECT and SET at the same time. The ESN will display on the screen.
