Hi All - I'm installing a USA Spec BT45-HON3 in the trunk of my '05 TL. The bluetooth audio functionality is working great. One thing I've not yet done is install the microphone.

Are there any suggestions for how to get the microphone cable from the trunk into an appropriate spot in the cabin?

Thanks!

 

hey,

I routed two wires from the the trunk to the front.
One for my backup cam, and one for my turn signal mirrors.

The steps are as is:

1. Remove rear seat
2. Remove trunk side liner, you can partially remove it.
3. Now you can put wire through the cabin and the trunk, right by where the shocks are.
4. Peel back door weather stripping and remove the interior panels that run along the side.
5. Put wire along the side, and put back the interior panels to hide wire.
