Purpose of the CTEL Module???
This may be a dumb question, but I'm trying to understand what the purpose of the CTEL module is in the W221. I recently scanned my car and I have a fault code stating that this module is faulty. I do have the bluetooth puck in the armrest and my phone pairs fine with the puck and works through the system as it should. My voice command works also. The only thing I do notice is in the Navigation screen, under Data/Connection there is an option for Bluetooth which I can't seem to do anything with. Any input?
Thanks!
Thanks!

Did you ever double click on the fault to understand what the specifics are?-------The CTEL module is very complicated and you will be best served if you got off the rug and searched the web where there are millions of CTEL topics
