We’re planning to take the 4Runner on a road trip this month (NY <> FL) so I decided it was time to do something about navigation and better iPod/MP3 integration.
I decided to go with the Pioneer AVIC-F90BT because it had all the features I wanted at a reasonable price.
The Sport Edition has a 10-speaker single-disc JBL sound system, so in order to keep the OEM JBL amp I went with a PAC TATO kit for the audio connectivity, PAC SWI-PS for steering wheel controls and a Metra 95-8202 dash kit.
The PAC units were very easy to work with, and a nice surprise was that the TATO came with a 4runner-specific harness for the SWI-PS and the proper R1/R12 and R5/R10 plugs.
The car doesn’t have the R9 connector for vss/reverse/park on the factory nav, so I had to tap into the main harness. I pulled VSS where it enters the HVAC ECU on A16 pin 8 (Violet w/ Red stripe). For reverse, I used 1F pin 10 (Red w/ Yellow stripe), which is the connector right next to the fuse box in the driver’s side lower panel. I ended up doing a hardware bypass so I just grounded the park wire.
I placed the GPS antenna on top of the HVAC ducting to the right of the center speaker, it seems to be pretty secure there and I’m getting great signal.
I was a little worried about how the Metra kit would fit (having read some horror stories), but it isn’t too bad. I didn’t have to trim it at all and my only complaints are the small gaps at the top and bottom, and that it sticks out very slightly further than the stock plastic surround.
In those pics you can also see the TATO (black box) sitting on top of the wiring harness, and the SWI-PS hanging down. After it was programmed I was able to tuck it down beside the HVAC ECU.
I pulled the driver’s side a-pillar trim to route the mic wire, that turned out to be much easier than expected as once the grab handle is removed it slides right off by just pulling the top towards you and wiggling a little to free it from the dash.
