theaftermarketradio.
3. Reconnectthenegativebatteryterminal.
Initializing the interface
Attention: If the interface loses power for any
reason, the following steps will need to be
performed again.
• Initializetheinterfacebyturningtheignitiononfor
30seconds,thenturntheignitionbackoff,then
backonagain.
Note: If using the ASWC-1, connect it after
you initialize the interface, with the key in the
off position.
