Hands free issues - "Bluetooth signal weak", eventually disconnects
 

Hi guys...

I recently upgraded to include Bluetooth in my car... I got the used TCU from a junk yard and the guy said it was what would fit my 03/4.4.

Everything appears to be OK, but when the phone connects, a few seconds later I receive the message "Bluetooth signal weak" on the phone and it eventually disconnects.

Am I missing something?

Any thoughts would be greatly appreciated!
