Both the radio and the climate control in my car are wacky. Take this to whom?

the dealer will specialize in you make in model, meaning they normally only see those types of cars (toyotas) however, if you take it to a reputable service shop, they should be able to do the same work for a little less than the dealership. (providing you dont already have a service agreement through the dealer already)

Whatever you do, insist on a binding cost estimate before any repairs are done, so they do not make any repairs you do not want them to make and by that make it more expensive. Also, you may want to get a list of everything that has been repaired and then take it to a second repair shop to verify that they actually did.

I don’t know the answer to your question. I just want to thank you for using the objective case properly!

Good luck with the car thing.
