I have a problem with my BT unit. I have a professional telephone kit (SA638) with Motorola telephone in cradle and I would like to change it to a MULF high module for BT support and USB playback.
I changed the BT unit, runned USB playback successfully but the BT isnīt working :-(.
I tried to remove $638 from a VO, tried to code there $6FL, $644 or $640 but still no success.
In a bluetooth menu I still canīt enable BT comunication field and I am receiving SOS call button error.

Does anyone know what all do I need to code when changing a new BT unit? Thanks a lot for helping me with fixing this problem!

Sounds like my car
I have the same phone, Motorola, and cannot use any other phone, just the SIM in the car..
So I installed Dension GW500 with bluetooth, but struggeling to figure out how to get this working.
I have the same as you now, SOS call button error.

Do you have the same setup?

I'm not sure if this would work for the new MULF but when I replaced my TCU from a non BT to a BT enable one, I had to add +K633 to the VO in both the CAS and LMA. After that, I coded the whole car and viola - it worked.
