Hoping someone can help me narrow this down.

problem is no audio from cd or radio.
bigger problem, audio from navi voice works fine.

thought it was the amp, but the navi voice goes through the amp and works fine.

could it be something internal in the headunit? should i even try to get that fixed or does the whole thing need replacement?

if it did need replacement, would an 05 navi fit? i'm gonna search that one...
