Re: Disabling cellular modem on 2014 8.4AN?
I wonder if their is a cellular antenna you can disconnect, it might be integrated into the air card though.
Or perhaps a simple jammer. Google jamming CDMA. Since it's close range it might not be too hard. EDIT: Never Mind, it's illegal and hard. Only way is by shielding.
Lack of cellular service will not make the head unit fault.
You could disconnect antenna, just as a test to see if the Antenna is even being used.
