After-market radio

I've tried to find a thread on this subject, but haven't been able to. a number of similar issues, but they didn't answer my question. I have a 2001 Town Car Signature with an Alpine sound system including a CD changer in the trunk (the dash unit has a cassette player). Question: is there an after market unit with built-in Bluetooth that will work in my car? If so, who makes it and would it be a pain to install?

Thanks for any help

There are a lot of aftermarket head units on the market that have blue-tooth capabilities, but depending on how old the CD changer is, it may not have the correct provisions for that specific changer. The best bet is look for an Apline head unit that has changer inputs for your model.
