What it is: (from the site above)
Absolutely flawless. I'm currently using this unit with a SWI-PS ( plugged into a Pioneer AVIC-Z1 ). Works great to retain use of my steering wheel controls. Nice OEM Feel!The SWI-CAN is an add-on module for use with the SWI-X, SWI-ALP, SWI-ECL or SWI-PS. It is used for steering wheels that use a dual wire CAN bus to control the factory radio. The SWI-CAN interprets the data to a usable signal that the SWI-X can use.
MUST HAVE THIS UNIT IF:
- You are installing an aftermarket radio in your CAN Bus vehicle and wish to retain use of the Steering Wheel Controls
- This is not designed to be a stand-alone unit. It must be used in conjunction with a SWI-PS, SWI-ALP, SWI-ECL or SWI-X. Check the Product link above for application details.
