The BT in my 08 isn't all that great. No one can ever hear me and I end up using speakerphone. I have been babied all weekend by a 2018 MB C300 loaner and it's 10 years newer tech.

Any rec's on some aftermarket units or additions I can look into? Streaming BT isn't a concern, I just want to be able to talk on the phone with it.

Thanks all.
