[AC Question]

It paired with the phone but will not take commands.

Not all Bluetooth devices work with all other Bluetooth devices - there are Bluetooth profiles, and the phone and car have to each have one for calls, one for contacts, one for commands, etc., etc. If the Tucson doesn't have a command profile, and there's no Hyundai update for it, you're stuck with what you have. (See your Hyundai dealer's service department for updates.)
