8900 sound delay when making and receiving calls
 

I have had my 8900 for about a year now and it has worked flawlessly with many blutooth systems. I just installed the new clarion dvd/nav/blutooth which the clarion site is showing compatibility with my 8900 and I am having a large delay of up to 15 seconds when making and receiving calls. Both displays show I am connected but I cant hear anything and they cant hear anything on the other end either. People are hanging up because they think we have a bad connection.

Any advise would be a help
