30 TMAA04-05 Ignition Sense Kit
The TMAA04-05 ignition sense kit provides a
mating plug for the radio’s auxiliary connector.
The four metre length of cable from pin 4
(AUX_GPI3) of the plug connects to the vehicle’s
ignition signal.
Once the kit is installed, the ignition signal is used
to power up and power down the radio, so that
when the vehicle ignition is turned off, the radio
turns off. When the vehicle ignition is turned on,
the radio is programmed to either turn on, or to
return to the state that it was in when the vehicle
ignition was turned off.
Important
The radio does not meet the IP54 protection standard once
the bung for the auxiliary connector is removed. Therefore,
once the TMAA04-05 ignition sense kit is installed, mount
the radio in areas where it is not exposed to water, dust or
other environmental hazards.
