The unit is a Pioneer head that fits the factory location in my 4 runner. The unit plugs in to the factory harness allowing you to use steering wheel controls without the PAC adapter. The cool thing about the unit is the addition of 3 RCA outputs one with sub control on the factory head. The head has many of the same features of a mid line You can print yourself a copy of the T1808 manual from there and check out the features of each Scion Pioneer radio from the T1805 thru the newest head units and even the Scion Pioneer navigation unit.

After quite a bit of research I learned that this one is not aux capable, just the later versions that came in the 06. It seems that anything should be possible so I am wondering if anyone has successfully added The T1806 sounds incredible compared to the original head unit. I thought I would need new speakers also because the old head unit crackled when volume was turned up moderately. Speakers sound brand new. Crisp and clear. Cannot believe the difference this $60 head unit made. PIONEER DEN-P2530 stereo wiring connector . PIONEER AVH-P5750 stereo wiring connector . PIONEER DVH-P5000 stereo wiring connector harness .

In the manual for the base Pioneer HU, the T1808, from the 2009's, it says the "Maximum power output" is "40 W x 4". Is that the same as 40W RMS going to the speakers? I'm looking for rear door speakers. Thanks. This is an older thread, you may not receive a response, and could be reviving an old thread. Please consider creating a new thread.
