2001 CL 500 - Factory bluetooth system installed .Worked great until a few days ago. Here is the problem: I can ask for: "Dial name" - "Name please" comes back - I give the name - The number is being dialed correctly, I can hear the phone ring on the dialed number (on my landline, but no sound when answering) When dialing from the landline to my cellphone - bluetooth connected - Cellphone rings, the comand screen shows incoming call but when answering through the steering wheel or the cellphone, again no sound. (Confused ?) Any help/suggestion would be very much appreciated.
