Disclaimer: Installing an aftermarket radio in your Acura TL will result in the loss of factory route navigation guidance, the loss of center channel audio and the loss of certain hands-free functionality within the factory system. All these features are easily obtained in your new aftermarket radio along with an amazing improvement in sound quality.

On Acura’s from 2007 to 2008 you will find connector A, C40 & D(antenna connector).

The 2007 to 2008 Acura TLs do not have pin A10 instead the power antenna 12V signal must be connected to pin D3. Pioneer radios only provide one blue wire for amp turn on and power antenna connect both blue wires D3 and C3/C35 to that blue/white wire to have full functionality. Kenwood’s and Alpines offer an amp turn on wire along with a power antenna wire be sure to match each wire to the correct one.
The steering wheel control interface needs to connected to pin A8 Steering wheel control positive, with our harness pin A20 is already connected to ground.
