In order to update the firmware on your PAC or Stinger module, click here and follow the steps outlined under your product.
This will ensure optimal performance and latest features for your interface while enabling it to work in the latest vehicle applications.
If you have a blue Radio PRO interface, it will require the PAC-UP Module (Sold Separately). All other modules only require a data transfer capable micro USB cable.
