Sorry to bring an old post to life.
I am looking for two things for my Tacoma original stereo setup: An aux bluetooth adapter, and a sound booster for the aux input. I barely hear anything when driving on the freeway.
It would be awesome if I find something that combines both.
Thanks.
I assume the aux input is a 3.5mn audio jack? If so the suggestions in this thread are good.
The following applies to both a patch cord or a Bluetooth adapter.
As far as a booster. I don't think you should need one. When using the 3.5mm headphone jack to patch into a aux jack, the volume is controlled by BOTH units.
With everything connected, turn the volume on the car all the way down. Then turn phone music volume all the way up. Start listening to something and slowly turn the volume of the car stereo up. It should have plenty of volume at lower levels now.
The iPhone's remembers volume levels for different audio sources. So when you disconnect from the 3.5mm the volume of the phone should drop down to what you had it set to with nothing connected.
