Note

After the power switch is turned off, the multi-media module receiver assembly records various types of memory and settings. As a result, after turning the power switch off, make sure to wait for the time specified in the following table before disconnecting the cable from the negative (-) auxiliary battery terminal.

Waiting Time before Disconnecting Cable from Negative (-) auxiliary battery Terminal
Condition	Waiting Time
Vehicle enrolled in telematics system (w/ Telematics Transceiver for G-BOOK)	6 minutes
Vehicle not enrolled in telematics system (w/ Telematics Transceiver for G-BOOK)	1 minute
