bluetooth

Hello, I recently bought BMW z3 with c33 radio. I want to add bluetooth module. As far as i know connectors are the same as in c43 radio will such module work? Has anyone tried it with c33 radio? https://www.amazon.pl/dp/B0C1CDV6CV

I have a bmw z3 from 1999 and want to put the original radio back in because the Sony one I have now looks like it’s from a spaceship - I wanted an original look and I saw that the blaupunkt radios don’t sit flush with the rest of the plastic - I would like to install Bluetooth into the original...

Some owners have put in a Dab head unit or are thinking about it, just wondered what the advantages of Dab are over streaming Internet radio from your mobile phone?
