It really depends on where the modem is.
In some Ford vehicles, the Telematic module has a separate fuse and can be removed.
Would need more information, (year, make, model, etc). To look over there networks and schematics to be more specific.
Were you able to find anything? I have no clue to make it happen but I would be willing to pay someone to do it
I will have a chance to look over the schematics tonight.
I've been working 18+ hour days lately.
Clearly you are hustling. Skip it and relax tonight fren. Take some time for yourself and your family. I'll touch base with you later this week. Get some you time.
