No, we lost what little ability we had to do that when manufacturers abandoned the globally used single and double DIN radios for tightly coupled and proprietary systems tied to each individual car. NOTHING on current cars control and "infotainment" systems is upgradeable or changeable by the buyer anymore.

Oh, and a reminder: Stand for freedom and NEVER buy a car that has a data connection (Internet or private radio) back to the manufacturer. I want my car talking to its manufacturer (and by invisible proxy, the big ad tech corps, governments, and insurance companies) exactly never.

(I think it is not trivial to buy a dumb TV set that doesn't phone home… that'll soon hold for cars as well, I'm afraid.)
