Magnadyne Radio-Safari Simba Gas

[krf9113]

Can anyone tell me if the Magandyne radio in a Monaco manufactured coach will receive Siruis from the get go? The operations manual states that it is "Sirius ready", which to me would mean that it needs additional components to make it operable.

If it is ready to go, where would I find the antenna? I'm going to use a portable XM receiver vs. the Magnadyne so if there is an antenna, I believe I can purchase an adapter and use it on the Onyx.
Also, any suggestions are welcome.

My sirius ready radio in my Simba did not have capability to receive until I added some component to the unit. I tried sirius on my car and decided it wasn't worth the effort.
