Audio won't turn on

Your vehicle has a three year ... 36000 mile warrantee on the sound system... "ENTUNE"

WHICH (OH-BY-THE-WAY)... has a ton of customer complaints against it...

My very best recommendation is to RUSH it back
to the dealer for warrantee work

This means that your vehicle requires service. Something is wrong. You can take it to Autozone and they will put it on their diagnostic machine for free. And tell you what is wrong. Usually nothing major. Just needs to be checked out.
PLEASE RATE by checking one of the 4 thumbs ups!
Thanks! Have a GREAT DAY!!!
