Re: Question for Alpine CDA-7998 owners
Make sure the constant power (yellow lead) is energized when the car is on or off so the unit can maintain its memory settings. Perhaps you might have an intermittent connection.
Check the fuse at the fuse box and on the battery lead as well with a DMM for continuity.
