Thanks to those that referred me to the long thread about the possible OEM "like" installation of Siruis XM using a model X or model S tuner. I read it from beginning to end but did not find a conclusion about new Model Ys with Ryzen processor. The discussion was mostly by those owning a Model 3 Tesla. The consensus was the Intel version of model 3 is doable with a tuner exchange and some antenna upgrades but new Ryzen model 3s were not producing sound. As I look at the images of tuners for Model Y and Model S -- these tuners appear almost identical except model Y lacking only one additional brown antenna jack. -- I assume that is the XM radio antenna jack? Has anyone successfully swapped the Model S plaid tuner into a Ryzen Model Y and achieved a working Sirius XM -- working sound and all?
