The stock radio can neither blue nor tooth Pete. Also doesn't have any rear inputs.
You can send it off to an outfit called Iron Cross Audio for some re-work though. They can make the radio both more robust against some internal damage that some tended to accumulate over time and add what you're needing for extra connections. Depending on what options you choose you'll spend $$ to $$$$; or, with the new tariffs we are imposing on all things, ££££££.
Alternatively, but perhaps no longer possible after the UK follows Canada and tells the US to take the piss, there is also
Something Entirely Different to completely replace the existing radio with something that is, well...., not the piss. At the link below is a total replacement that is both monumentally modern (compared to Harley [though not the world]) and does all you're looking to do including having both blue
AND tooth in the radio.
