TranzIt Gain Adjustment
1) The TranzIt is designed to install inline with the radio antenna connection usually located
on the back of the radio in the dash. In some cases this connection may be at a remote
radio tuner location. Consult vehicle manufacturer’s information in these cases.
2) Some antenna connections require the use of an antenna adapter in order to connect the
TranzIt. These adapters are available from most car audio installation retailers.
3) Select the FM frequency where you will access your new audio device. On the side of
TranzIt where the label indicates “Tuning Frequency” there is a two position switch. Note
the position of the switch before installing the interface.
If you have a local radio station that occupies either of these frequencies (87.9 or 88.3)
please move the switch to the position that does NOT match the local station.
The position of this switch determines the frequency where you will access your new audio
input. We recommend choosing one option, and setting one of the radio’s preset buttons
to represent that station. This easily accesses your auxiliary audio input by pressing the
preset button.
Using a multimeter, identify 12V+ and ground wires behind the radio.
a. Connect the TranzIt red wire to 12V+ (accessory)
b. Connect the TranzIt black wire to ground
c. Connect the vehicle’s antenna into the TranzIt antenna input*
d. Connect the TranzIt antenna output into the radio*
*A vehicle specic antenna adaptor may be required to make these connections
The rocker switch supplied with the TranzIt will turn the device on and off. When the switch
is in the on position, the TranzIt will interrupt the incoming antenna signal to deliver the
cleanest signal possible from your device through your FM radio. To regain standard AM/
FM reception, move the switch to the Off position.
4) Once the TranzIt is installed correctly, be sure to properly set the audio level. When set
correctly, the audio level of the TranzIt will match the volume of typical FM radio stations.
On some models of iPod you will need to enter the video settings menu, and select TV
out, and set this option to “ASK”. When a video is selected to play, the iPod will ask
“do you want to enable TV out?” select on, to view video on an external screen using
this product.
Some newer models of iPod, iPhone, or iPad do not have this option in the video
settings menu. Instead, after connecting your iPod, iPhone, or iPad to our product,
and selecting a video to play, the device will ask you automatically “Display on TV?”
Choose “YES” to watch the video on an external monitor.
