18 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 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 the 
radio turns off when the vehicle ignition is off. 
This avoids any possibility that the radio may 
flatten the vehicle’s battery. When the vehicle 
ignition is turned on, the radio either turns on, or 
returns 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
.
