Replacing JBL Synthesis head unit, keeping factory XM

I have spent a lot of time looking through threads/posts regarding adding XM radio using a factory radio module and fit kit, and I have read a lot of threads regarding keeping the JBL Synthesis system and swapping in an aftermarket head unit while keeping steering wheel button functionality using an iDatalink Maestro RR adapter and HRN-RR-TO1 module, and even threads on adding the Bluetooth right-side buttons if your steering wheel doesn't have them - I'm adding mine this week as soon as they come in.

What I have not been able to find, however, is information confirming whether or not using the iDatalink modules and installing the Kenwood DDX9903S head unit I want, or any other head unit for that matter, will retain control/use of the Toyota XM radio module.

A call to Crutchfield resulted in the rep confirming without a doubt that it WILL work, while the local installer that I plan to use confirms without a doubt that it WILL NOT work.

Even referring to information found on iDatalink's own website returns ambiguous answers, with the installation instructions detailing how to bring up XM Radio on the head unit during installation, but then a checklist of compatibility with factory functions preserved on a 2006 4Runner Limited with the JBL Synthesis system omitting a check-mark next to "Satellite Radio".

Has anybody with a 2006-2009 T4R with the JBL Synthesis system that has the factory XM Radio module swapped out head units using the iDatalink modules and can confirm for me if it will or will not work?

I am skeptical about the confirmations that it WON'T work because my wife has an FR-S with the Bespoke / Pioneer head unit, and calls to Scion confirmed without a doubt that XM could not be added to that car. That head unit is used in other Scion cars, and they reportedly had XM capability, so I simply ordered her a TC fit kit and module, and had the local installer add it to her car, and she has been rockin' out on XM with it for close to 5 years now.

Some of you may ask "Why is he so determined to use a factory XM module with an aftermarket head unit instead of just buying a module directly compatible with his new radio?", to which I answer: "Because lifetime subscriptions." Both modules in our cars have lifetime subscriptions which were purchased years and years and years ago, and in an effort to generate revenue, XM has stated to me that they will not switch the lifetime subs to any other hardware for me again. Ever. I'd really hate to lose my "free" XM.

Sorry for the long post, but to ask again: Has anyone with a 2006-2009 T4R with the JBL Synthesis audio system and XM successfully swapped head units and kept the XM function?

Thanks!

Well, the right side button module and cable came in today, and had them installed in 15 minutes. No kidding - it's that easy. Super, super simple. I felt no need to disconnect the battery - nothing in the steering wheel to set off the airbag. Especially with the ignition off. Except if I worked really, really hard to somehow make a connection from the horn circuitry to the airbag terminal in just the right (or wrong, as it were) way. I just slipped it up and laid it over the steering column - the wires are plenty long to do so without putting any stress on the connections. The #30 Torx screws are even held in place by the plastic surrounding them, so the only hardware to really keep up with is the two Phillips head screws. I'd make a step-by-step writeup, but that has already been done several times, and done well, so I'll just put a link to my favorite right here:

I suppose nobody else that has read this has replaced the factory head unit and attempted to keep the factory XM module. I'll play guinea pig and post results after I'm done. Worst case is I have to get a Kenwood XM module and start paying for the service, or I could just dump XM altogether and stream music through Bluetooth. I may have a lifetime - subscription enabled Toyota XM module for sale. Who knows. Details to follow later this summer.
