Got my car back from installer today, my plan for the sirius xm touch commander failed. The cars antenna ended up being the black 3 prong connector that is circled, not the lower one that I thought would have been it. Had the antenna plug been the traditional type the touch commander should have worked. The other option I tried was ordering a bluetooth transmitter from amazon (
https://www.amazon.com/gp/product/B01N5KKUR0/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 )that would plug into the touch commanders aux jack and convert the signal to bluetooth. The transmitter would eventually pair with the model 3 after several tried and I could play music from an iPads headphone jack through the transmitter and to the model 3 stereo. This method was not reliable it would have a hard time reconnecting after I'd turn the car off and come back, so I returned the transmitter. Only other option would be for an aux to fm transmitter but I've heard that none of the ones today are very powerful due to FCC regulations. I did however get my Valentine One radar detector hard wired. He tapped the light blue gray wire in the kick panel that powers the 12v outlet. Am currently using the stock suction cup mount to hold it on the windshield until my blend mount arrives next week (product was supposed to be shipping today) Can post photos when completed.
