Didn’t work, doesn’t you have a part number for a style of VCImM that we know functions for certain? I may just need a different part.Give this a whirl …

Found this ol bit of info related to too many users added into the VCIM for bt.
Press the push to talk button. Say "Hands Free" then at the next prompt say "Bluetooth". Then say "List," which will provide the nametags of all the phones paired. Now start again with "Hands Free" then "Bluetooth" then say "Delete" and give the name tags of the phones to remove.
If neither of those cured it the cause may be that the VCIM module with just one antenna input is not capable or pinned out differently than the version with two or three inputs.
