Yes -- IF the transformer did not pick up magnetic fields from the 
vehicle's systems.  I saw that when doing testing of some pro mics for 
RFI in a Volvo S80 -- the output transformer in the mic was not 
shielded, and picked up trash.  That would be fixed with a transformer 
that has a mu-metal shield, but shielded transformers are expensive.
