Seriously I found the answer to Sirius
 

If you go to http://www.tss-radio.com/products/land-rover-kenwood-sirius-tuner-package they sell a package that allows you to use your stock stereo to receive Sirius radio.
The package comes with a Kenwood Sirius receiver, antenna, cable and Pie interface adaptor, the best part is you don’t even have to remove you stock stereo to hook it up.
Plug one end of their cable into the Kenwood receiver, connect the Pie interface adaptor to the other end, and now plug the interface cable into the 10-pin connector under the passenger seat for the CD player (no power necessary). Throw the antenna on the roof and call Sirius to activate (or you can activate on line).
The Sirius programing will show on your stock stereo, you can use the stock steering wheel controls for volume and channel changes. Oh and it you want to keep your CD there is a slave port on the receiver that you can hook you CD back up too. The Kenwood receiver also has a two female RCA jacks. The Pie interface cable and comes with a second cable that has two male RCA connector and a male 3.5 mm ?? Plug; which I assume plugs into an mp3 player.
So you don’t need and aftermarket stereo that just doesn’t look right or has the wrong colored lights, no special adaptors to get your steering wheel controls to interface and other than the antenna you can’t tell it’s there. I left mine under the passenger seat were the CD player would be, but the cable is about 8 feet long so you could put it just about any were in the truck that you wanted.
Now it does not give you all the functions of a new Sirius stereo, like logging artists, playback & repeat. It probably does more but I would have to read he direction and you know that any going to happen. It takes a minute to get use to the how the head unit reads, for instance channel 41 would read cd track 4 song 1.
But what is does do is allow you to have satellite radio using all the stock Harmon Kardon equipment and you can be up and running in 5 minute or less.
Best of all it only costs $119.99 OR $89.99 If you’re a new subscriber, I feel like I got ripped off I have a life time subscription and some one new can buy the equipment cheaper than me. Oh well; at least I get my satellite radio & up to date traffic reports back, terrestrial radio sucks.

Siriously? :)
Sounds good.

radio is dead. i stream internet Slacker from my cell phone to a cassette adapter. I use Google maps for up to date traffic.

has someone mounted an ipad in their truck yet?

I used a cheap Sirius unit and mounted it to the ashtray, then ran the wires to the antenna port for direct connection - better sound quality. I have to say though, if I had an AUX in, I would use that exclusively as I prefer PANDORA over XM/SIRIUS.

Wow, that's really cool. Esp having the steering wheel controls. Great find drow.
