Installing SiriusXM on Regular 2013 Touchscreen

Hi everyone. This is my first post on TW.

I have a 2013 PreRunner Double Cab w/ TRD Off-Road Package. So I don't have the SiriusXM/SAT button in the top right corner of my head unit. I bought the SiriusXM Onyx EZ radio, but returned it after 1 day of use. Sick of dealing with the bulky power adapter, and not to mention the ugly magnetic antenna that came with it. I would even much rather mount a "shark fin" antenna rather than use the magnetic one.

I found a few threads (i.e. installing sirius on stock touch screen radio) mentioning a couple of kits (i.e. VAISTech's Kit). This kit is great, minus the same cheap antenna that I could get with any SiriusXM radio.

If anyone knows of any kits, whether it's a kit from Toyota or an aftermarket kit that would allow me to do this with my current HU, any information you could provide would be great. Thanks in advance. I'll also keep this thread up-to-speed should I find a solution before one is posted.
