The Handsfreelink control unit has died. You should asked the dealer to ask Acura for help in replacing the control unit. In this business atmosphere, Acura should help you if the car is out of warranty. Just ask the dealer to help you out in a nice way.

 

Certainly worth a shot. Dealer may be able to work with you and help you out outside of warranty - it's called goodwill.
You just want to make sure they don't stick you with a fee for an hour of diagnostic work and not have it covered under goodwill.
