I would suggest calling or find online Crutchfield. They have been car stereo experts for many years. They sell harnesses for just about any car allowing you to plug in your stereo directly to the existing harness. I guarantee they will know!

Hi XX,

Let's try the easy ones first:
1. try to do a reset of the unit;
2. check that all the speaker wirings are:
2.1 connected properly following the wiring diagram;
2.2 not bare/exposed and touching any metal part/chassis;
3. verify that the MUTE is not enabled;
4. try all signal sources: AM/FM, CD, SD Card, USB, AUX;
5. verify that the SEL is set to SUB OFF;
6. replace the CR-2025 Lithium battery of the remote.

If your concern has not been corrected after completion of the above procedures, you may need to:
a. open the unit for a loose connection and/or other diagnosis;
b. ask assistance from the manufacturer's Technical Service at 1-800-445-1797;
c. return the unit for a replacement.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
