Radio Replacement and
Steering Wheel Control Interface
for Toyota / Lexus / Scion Vehicles
RP4.2-TY11
1.
Turn the ignition on. The LED on the interface will turn on and the +12v accessory wire will turn on.
2.
Turn on the radio and check volume, balance and fade.If you do not hear any audio you may need to cycle the ignition to
initialize the factory amplifier.
3.
If the overall volume is too low, use the gain adjustment on the side of the RP4.2 interface to set it to the desired level. The
best way to do this is to turn the volume on the radio to 3/4 volume, then turn the gain on the RP4.2 until some distortion is
heard, then back it down a little.
4.
If you have a JBL system and there is no audio, please make sure the Blue / White remote wire in the radio connector is
hooked up properly. If there is still no audio, reset the interface according to the procedure in the next section.
5.
If fading is acting inconsistent, please ensure that all speakers are connected to the proper polarity.
6.
Verify that all SWC are functioning properly. If any of the SWC are not functioning properly you may need to reset the
interface or follow the re-calibration procedure above.
7.
The LED and radio will turn off when the ignition is turned off.
