I'm not sure what model your 'new' one came from, but I believe XM was only available on 2006 models with Sunroof & Navi. In those models, the XM receiver is located behind the back seat. They do indeed hook up to the roof mounted antenna. If that's the case, maybe you can get him to pull the seats/panel & retrieve the XM receiver for you to work with.

I don't know about the XM "Kits" at all (dealer installed), but you can get them at Handa.com, antenna & all.

If the 'new' one came from a 2006 RTL with factory XM install, then it will have a navigation display screen (only available on Sunroof/Navi models).
If it is NOT from a navi model, then it will not have had the XM from the factory (would be "XM-ready" instead), but would rather be subject to the dealer kit. How aftermarket kits compare to those dealer "accessory" kits, I haven't a clue (sorry).

Anyway, I'm fairly certain the above is correct, but I'm sure you (& I) will hear if it is not. I don't know how things were offered after 2006 (I know they all had sunroofs!), but maybe you want to find out what year & model your new radio came out of.

The Unit I purchased came out of a RTL with a moonroof, no nav. As near as I can tell, there is no way I can interface the XM receiver I purchased from Crutchfield to the headunit I just purchased from typesfanatic. I would be able to do it with my original factory head unit, however.

At this point, it would be easier to swap out my factory unit with an aftermarket headunit. Thanks for your help, dnick.

WHAT YEAR RTL??? Is it a US model (not Canadian)? Since it's not a NAV unit, it will have a place on it to add XM, assuming it's the same as 2006. See if there is a place on the back for a 14pin Bus cable connector. There should be. That is what will interface you with the XM receiver (You do NOT have an XM receiver inside that unit, no matter what.... even the factory XM/Nav HUs have XM rcvr remotely placed!). I believe if it truly does NOT have that connector hole on the back, it must be either a Canadian model (not sure, but have read XM is not available in Canada), or is NOT from an RTL. (I could be wrong about that)

Check out the install instructions at handa.com (I've provided link below)... it should give you a pretty clear idea of what you are looking at to get XM hooked up to that unit (you DO need an XM receiver, either scrounged from an old RTL w/Navi, or bought separately or with an install kit... like the handa.com pdf shows). I guess the "add-on" receiver location for these kits is under the front seat (see instructions) vs. behind the back seat as in factory install.... in factory units the Nav unit takes up the space under the front seat, so XM rcvr gets relegated to behind the back seat). My guess is, the Crutchfield guys should be able to help you know exactly what to do, once you're well versed in exactly what you have in hand. "Most of them" are pretty sharp with this stuff. It's doable.... just have to decide what you want to do. Between their guidance/instructions, and the handa.com OEM kit instructions, you should be able to formulate a plan.

Here's link to install instructions: (DO LOOK AT THESE!)

and here's the kit from handa.com (don't know what Crutchfield kit might be equivalent.... but you might already have it).

Hit me in the head! I just noticed that the listing for the OEM "Kit" on Handa.com (pictured above), states "2007-2011".... and does NOT include any 2006, which would exclude even the RTL! I guess the non-Navi (non-XM!) RTL in '06 was NOT XM-ready..... which of course reflects everything OP has observed & listed here so far. 'Still puzzling that the connector is on the back of OP's radio though.... maybe they were in the process & that was for "future use" when they finally got to "XM ready" in 2007. Interesting how that all evolved.
Now I'm still wondering if the Canadian models are the same or not (as US). Who knows about these little things.
Anyway, all for naught at this point. Good luck with your aftermarket adventures.

EDIT: Follow-up.... I see that the listing for this XM Kit on Bernardiparts.com actually does include 2006, but specifically excludes RTL! Interesting.......

This is so bizaare.... what a strange set of info on this topic. Way too many confugurations for me to sort out. I guess I stand corrected. Checking the parts lists for these models doesn't seem to help much clarifying this information.

BTW, IS the XM unit (receiver) actually IN the HU of those radios you guys are citing????? Or is it not behind the back seat, as it is in RTL sunroof/navi????? (next to subwoofer enclosure)

I guess I can imagine that they only put it there due to loss of space to the Nav unit...... but I'd be very much surprised by this.


I wonder if our friends at HandA have any more refined expertise on all of these variables???? Help Guys!
