2005 Accord EX and adding XM radio?

I just leased a new 2005 accord ex sedan with the am/fm cd changer. I was
thinking of having an after market XM radio set added. Does anyone know if
the radio that is in the accord is xm ready? I looked at the tweeter website
and noted that tweeter has the satellite unit and adapter for $49.00 each
and then the antenna is only $35 dollars, so with installation I figure
$200.00 tops. The monthly fee went up to $12.95 a month, but that's not bad
considering you get 150 channels.

1. My biggest question is can I keep the same radio without having to add a
separate tuner?

2. Does anyone know if Tweeter is good place to go to? I figured they are
pretty reputable.

3. Do I have to be careful because of the electronics in the car and the
warranty?

Thanks,

Tom

 

I just bought a '05 EX, and yes, it is XM ready, they even give you a
free 3 months of XM radio.

 

Mine doesnt have the XM antenna or the unit, so that is why I want to get it
installed but just wanted to make sure the radio is ready as well.
