After noticing the offering of Homelink for $300 on the Tesla store, I'm hoping that's just the beginning for us SR/SR+ owners. While the Homelink is not an item I'm necessarily interested in, I would absolutely pay for the web browsing/music capability and Elon couldn't take my money fast enough if they offered an audio upgrade that included additional speakers and the subwoofer. With the plan of having SR/SR+ vehicles the bulk of sales, I would guess that those offerings could bring some much needed revenue.
