I just got my 04 prius with JBL and Navigation and want to change out the head unit. So i just have a few questions. Since my head unit is double din, I know i need this kit: h t t p ://w w w .amazon.com/Scosche-010TA2103B-2004-up-Toyota-Double/dp/B002G53BCG Correct? Secondly, I have the 9 speaker JBL system and want to know if there is a special harness I need or will a basic harness like this work? h t t p ://w w w .amazon.com/SCOSCHE-TA02B-Wiring-Harness-Toyota/dp/B00009UHKW/ref=pd_bxgy_e_img_b Three, What is the best way to get the steering wheel controls to work? Four, how do I keep the MFD there and use it just for information rather than a head unit? I read something about a resistor trick, but is there a harness that will keep it working? thanks
Just did mine, and as far as special harness yes tato makes one for the jbl system or you can do what I did if your going to install after market speakers and amps have them bypass the jbl and you don't need it. My head is providing plenty if power to my speakers now I can only imagine how it's foing to sound after.
I did the resistor when putting in a separate headunit (behind the fold-down-door below the original radio which I left in place but unplugged. I think I put the resistor IN the plug I pulled out and taped it up). http://www.pac-audio.com/pacproductdata/tato/3_tech_briefs/prius_fix_pac.pdf
