Crux SWRSU-38C User manual

  • Hello! I have reviewed the user manual for the Crux SWRSU-38C Radio Replacement module. This manual details how to install this module in select Subaru vehicles to replace factory radio while preserving key factory functions, including steering wheel controls, StarLink, auxiliary input, and the backup camera. I am ready to answer any questions you might have about this device and its installation.
  • What is this device for?
    What factory features are retained?
    Is an antenna adapter included?

SHIELD to SWC Ground
For aermarket radios that have wires for SWC connecons, cut o the 3.5mm plug on the Crux SWC Cable and connect the
SWC wires as follows:
Note that there are some radios that only have
SWC1 and SWC2, in this case “shield” does not
need to be connected.
NOTE:
For non-amplied systems only.
STARLINK RETENTION:
To retain Starlink, separate the Starlink module from the radio and reconnect
the harness and antenna connectors to the module. Stu the Starlink module
back into the dash and secure it with zip es or tape to prevent it from raling.
NOTE: The front speaker audio will be lost if the StarLink module is removed
from the system.
There are 2 possible DIP switch sengs for the Subaru SWC as follows. Try the one that matches your vehicle.
