Thanks for the info.
I tried using Tool32 to check the bluetooth ID and it just shows some weird characters. I think the MULF2 may not have been coded for bluetooth since the weird characters seemed to be the default VIN numbers. There nothing in Tool32 for me to change the bluetooth ID as well so I guess I have to try to flash the unit to see if I can reset the bluetooth ID.
