Sirius XM Tuner to stock antenna? (2011)

I have a 2011 TRD OR, originally I had the JBL system installed, but that's long gone.

Now, I have a Pioneer AVIC-7200NEX that's HDradio, SiriusXM, etc etc etc ready. According to Pioneer, all I needed is the SVX vehicle tuner that connects Sirius to my Pioneer radio.

So, I plug the Sirius tuner into the back of the Pioneer NEX, then plug the Sirius antenna in and run it to the top of the dash (or out to the roof) for a better signal.

HOWEVER. I'm wondering if I can just splice into the stock antenna as these trucks come "XM-ready" even back in 2011. I have the shark fin on the back, etc. I'd still be using the Sirius XM SXV300 vehicle tuner, but I'd be using the stock antenna so I don't have to run that stupid square up to my dash.

Thoughts, advice, input?

 

If you actually have the XM antenna connector in the dash, you. Can absolutely use it. In many Toyota’s it’s blue, or a small white connector. Then Maestro makes adapters to convert that over to the plug on the Tuner.
You do NOT want to try and splice them. Just get the adapter.

 

Well originally my truck was XM ready, but that's before XM and Sirius merged or whatever. I've read the older Toyota antenna only goes up to channel 300, though.

So, I'm thinking I might just stop being lazy and do it right. It's literally a $50 tuner I already have sitting next to me. I just need to plug it into the back, then run the Sirius XM antenna up to my dash in the corner. I'd rather not run it outside and put it on the top of the truck, but that's probably the best spot for signal. What ya think @destin_meeks

To be fair, I already have the same square antenna on my dash in the corner by my windshield for the Pioneer's shitty map and nav system I don't use. lol. It works fine, but I'd rather just Google maps with my phone. Thinking I can mount the XM antenna next to it.

 

XM antennas are way more sensitive than GPS antennas (they require a constant connection to a satellite, where gps antennas just need to talk to one every few seconds to update location data)
So if you put in on the dash and are driving one direction, and the satellite it’s trying to connect to is behind you, it will have a lot of drops until it can find a new satellite to pair to in front of you (because the roof and back wall are metal)
This is fine on a long straight road, but becomes a huge pain on curvy roads or city driving with any turns.

 

I used the shark fin adapter on my 2009 and have been using the OEM antenna without issue since installing my first aftermarket radio on 2010.

The channel limitation is not the antenna, it’s the tuner. With the old tuner I was getting the Sirius package which did not have channels over 300. I’ve replaced it now with the current generation SXM tuner and all channels are available using the same antenna.

When you enter your tuner ID number into the SXM system, your subscription updates your available channels.

 

Ah ok. Thanks for the information guys. I went ahead and mounted it to the front center of the roof, by the windshield. Ran it through the weather stripping, down thru the firewall and I'm all good. So far it's pretty awesome, but I'm sad I didn't have the NFL channel. Maybe next year.

The radio options in Vegas changed recently and are terrible. I offroad constantly and lose service to where my phone apps don't work, and I do a lot of camping, hiking, fishing, or going to my cabin in Utah where there's no service either. Having to switch between radio/device/to the old iPod in the glove box is always a pain, especially while mobbing down a trail avoiding trees and rocks. And the touchscreen is impossible to work with while bouncing around.

So, now I have SXM to fix most of that. Big trip this weekend so we'll see how it does.
