I have a 2006 Toyota Matrix, automatic transmission, and am looking to get cruise control installed. I called the dealer, who said they won't do the installation and I have to buy aftermarket parts. As long as I get the right kit for my model, are all aftermarket parts the same? Where would I go to get this installed? And is there any risk that this will invalidate my warranty? (I've heard the install is relatively simple, but I am definitely a car novice.) If anyone has recommendations of shops in Boston, even better.
Thanks for your help!
