Initializing the AX-GMCL2

Attention! 

If the interface loses power for any reason, the following steps will need 

to be performed again. Also, if installing an ASWC-1 connect it after you initialize 

and test the interface/radio, with the key in the off position.

• Turn the key (or push-to-start button) to the ignition position and wait until the

radio comes on.

Note:

 

If the radio does not come on within 60 seconds, turn the key to the

off position, disconnect the interface, check all connections, reconnect the

interface, and then try again.

• Turn the key to the off position, and then to the accessory position. Test all

functions of the installation for proper operation, before reassembling the dash.
