Hi all,

I don't mean to Hijack this thread, but, don't really want to start another for a similar subject. I too have the 490 option code on my 2003 base model, with a CDR23 head unit, and I guess woofers in the door. Stuttcars lists the 490 code as Sound system (Harmann analog), does this mean the system is connected via the MOST bus or not? I want to replace the head unit, and, crutchfield advise to just wire the speakers directly to the harness, or will the Metra 70-1784 Receiver Wiring Harness suffice??

Regards,

Jake.

P.S. this is my option sheet:
