If you are the owner of one of the older Tesla Model S or Model X jalopies, you recently had the option to spend $2500 on an upgrade of the in-car infotainment system, which included new video and gaming features…but removed AM/FM radio and SiriusXM from the dashboard. No worries, though, because now, for another $500, you can get your FM radio back. (The radio restoration does not include AM, which the company says is “not possible.”)
