AUX option just quit working on my 2010 Mazda CX7 after no issues since I bought in 2014. Is this a dealer only fix (my closest dealer is 200 miles away), or hopefully an easy fix?
guessing the battery is old and of compromised grounding potential..and the unit needs to see a solid 12-12.5 volts to operated correctly...Just double check the grounds...loop eye connections turn green and don't conduct the full power...so get a new set of cables and clean the connection to them...and a new battery if yours is older then 5~
