have an 07 MDX Tech, starter went a few months back with a puff of white smoke from underneath. Ever since having it replaced I have no radio, no NAV, Keys will not unlock or lock doors, OBD2 port is dead. Any ideas where to look, I have checked all fuses and wiring connections and there are no problems. AC controls work and show on display. Red anti-theft light flashing on radio unit. I have tried pulling fuses and disconnecting battery to no success.
