I have a factory siriusXM sat radio receiver for subaru radios. Not sure of the model number (I will add it when I get it out of the car next week.) But it is works on my factory 2012 WRX Clarion Radio, and IIRC it originally came from an 05 forester. Pretty sure it works on most subaru models.
Why pay $400 at the dealer when you can put this in for cheap!
$100 + free shipping and I'll make sure I add the antenna (mine didn't come with one.) No brackets included, I just used a piece of duct seal to hold it onto the radio and its never moved.
please email or call/text, as I'm not on here too much. email@example.com 216-235-3421.
