Harper- Appreciate the help. That all makes sense.
Tell me if I'm wrong here...there are 3 options with radios in the 4runners...
1-bone stock radio (basic)
2-jbl option without nav
3-jbl option with nav
If this is correct, then anyone with option 2 should be able to use it?
Edit.....There is such a thing as a Limited that has JBL but no nav.
That makes 4 different stereo systems at least in 2010"s . I'm pretty sure(99%) 2011's didn't change.
1) AM/FM CD player with MP3/WMA playback capability, eight speakers, XM compatible (additional hardware & subscription required)
No steering wheel controls,Bluetooth or USB= base model
2) AM/FM CD player with MP3/WMA playback capability, eight speakers, XM® Radio (includes 90-day trial subscription) , USB port with iPod® connectivity, hands-free phone capability and music streaming via Bluetooth®wireless technology
3) JBL® with NAV(Option Only on Limiteds and TE's) ,AM/FM 6-disc CD changer with MP3/WMA playback capability, 15 speakers including subwoofer, XM® Radio (includes 90-day trial subscription) , USB port with iPod® connectivity, hands-free phone capability and music streaming via Bluetooth® wireless technology
4)JBL without Nav(Only on Limiteds) ,AM/FM 6-disc CD changer with MP3/WMA playback capability, 15 speakers including subwoofer, XM® Radio (includes 90-day trial subscription) , USB port with iPod® connectivity, hands-free phone capability and music streaming via Bluetooth® wireless technology
SR5's come with #1 or #2 depending on options/packages .Not wired for the JBL nav.,and that was confirmed with another member that wanted to buy my JBL Nav. It would cost big bucks to rewire it. Better to just get aftermarket ,like Pioneer, Kenwood ,ect..
TE's come with #2 or #3 ...If it didn't come with the #3 JBL Nav then it's not wired for it. That was confirmed with another member that wanted to buy my JBL Nav. and he had #2 stereo.
Limiteds come with #3 or #4 . Not sure if the wiring harness is a match.
