Swc Input Operation - Dual DMCPA70BT Installation & Owner's Manual

The built-in SWC Interface is compatible with PAC steering wheel control modules.
The PAC SWI-RC is recommended. A third-party adapter must be used in order for the
DMCPA70BT to be compatible with any steering wheel controls. The following controls are
available for most vehicles.

Note: Not all OE steering wheel functions may be supported by the DMCPA70BT.
1. Set "Radio Select Switch". Set the SWI-RC to position 7 - "Pioneer/Other/Sony".
2. To program, use the Pioneer/Sony/Other radio function mapping order for Dual units.
3. When programming the SWI-RC, if a function is not supported (or not desired), then the
function MUST be skipped as per the PAC SWI-RC instructions.
4. The SWC function MUST be programmed in the correct order per the PAC SWI-RC radio
function mapping order instructions.
