Noob here and wanted to thank everyone on this board for all of the great advice and pre-emptive trouble shooting for an AVIC-D3 install.
The only thing that I have not figured out is how to hook the ILL (dimmer) wire into the stock harness so the AVIC will dim automatically when I turn the headlights on and use the dimmer. I have searched the archives, have searched on toyota-4runner.org and have googled to no avail. Would someone mind helping me out here?? It's a 2005 4Runner Limited V8 4WD. Thanks!
BTW, I installed my D3 with bluetooth, ipod, XM, SWI-PS, and TYTO-01 adapter for the stock JBL Synthesis in my new-to-me 2005 4Runner Limited V8 4WD. This system is really pretty slick and all of it seems to work pretty well together. I put the XM, Bluetooth, and I-pod interfaces in the little cubby above the glovebox, which has worked out pretty well. I also ran the GPS and XM antenna to the back of the truck through the A pillar and around the various headliner moldings. The GPS antenna was just barely long enough to reach the headunit, but it did work. Lots of wiring with the SWI-PS, adapter, various components, etc.
