Where is the SiriusXM tuner located?

[UtahBrandon]

Does anyone know where the XM tuner module is and how easy it might be to access? I’d like to leave the original XM antenna in place, but add a new antenna somewhere so I’ll need to able to access an originating point for the new antenna cable. @flip, do you have any diagrams?

I’m thinking of trying a magnetic antenna mounted to a ditch light bracket. Anyone tried this? I might have to design my own bracket. My roof top tent has rendered my XM radio useless.

It will be in the standard head unit. At least that’s how it has been in the past.

The receiver is built into the module behind the infotainment screen.

The antenna itself is in the "halo" structure above and behind the rear passengers head, and then that antenna cable is run up front to a splitter located beyond the SYNC screen. That splitter will split the antenna signal and run it to everywhere it needs to go... APIM, ACM, & TCU.

• APIM - Accessory Protocol Interface Module (aka: SYNC module)
• ACM - Audio Control Module
• TCU - Telematics Control Unit

It's pretty easy to get at the Audio Control Unit... I have a video here. I didn't specifically point out the connector for the antenna, but it should be one of the two connectors on the driver's side of the ACM.

Edit: Also.... that antenna also acts as a GPS antenna for the navigation and telematics systems... in case that wasn't super obvious from the modules I listed above. Probably should have mentioned that earlier.

Thank you very much. Sounds like I would need to relocate the existing antenna, rather than replace it, to keep the GPS functionality? Dang it

Thank you!

Yuuuup.

If you were just worried about the Satellite radio, you could theoretically run a new antenna just to the ACM and left the rest of it alone, but if that splitter is an passive splitter rather than an active splitter you may run into goofy impedance/power issues.

Either way, and I'm sure you've seen from the files @Ksjrb03 posted... it isn't going to be a super straight forward task.

I think you can remove the splitter input into the ACM, wrap that connector in rubber and electrical tape ,leave the rest of it alone. Then input your new sat radio antenna into the ACM. (This is assuming you can get an antenna with the same input connector, I have no idea on that). Then report your findings here as you will be the guinea pig

I relocated and switched to an exterior SiriusXM antenna, but I am wondering if putting an additional splitter in would allow 2 separate antennas where you can have separate GPS and Sirius

The factory XM antenna only has a single coax connection. Are we sure the GPS is also inside the XM antenna? If so, I do not see how both signals are processed over a single coax.
