The purpose of this thread is to document the process of installing a 2012 Entune navigation unit into a pre-2012 Tacoma with or without the JBL system. Here is a link to the write-up. As of now it's just pinouts, part numbers, and notes but will be updated as I make progress on this project. Most of the information I looked up myself on the Toyota tech site, but I also referenced these posts/threads:
A lot of you would say "go aftermarket" and for the most part I would agree. Personally the JBL system is plenty loud and has all the functionality I want, plus it looks OEM. My Tacoma is a 2010 without the JBL system but I will describe the process for the JBL system as well (it's a lot easier than going from non-JBL to JBL).
This is for reference use only, if you mess up your vehicle it's not my fault. I am however willing to offer advice or help if you PM me. Ok so lets get started...
First things first: I purchased the Entune navigation unit, JBL subwoofer, and amp. Notice on the back of the headunit there are two boxes. The top box is "Display Audio". The bottom box is the navigation computer. I unplugged the navigation computer just out of curiosity and sure enough the interface changed to the basic display audio features.
Changing the backlighting color, this could be an entire write-up in itself so I won't go into too much detail. If there is enough interest in a write-up for that I'll do it. I like red because it doesn't ruin your night vision and it's better than the Tacoma amber/orange (or white in the 2012), the knobs might stay white. Still waiting on replacement tiny LEDs to ship but below you can see I already did the clock and hazard switch. The hazard switch was an incandescent bulb that I swapped out with a red LED I had lying around. The clock has three white PLCC2 LEDs that I replaced with red ones. The first two images below show the right and left switch/LED panels of the Entune unit. The third image shows how small the LEDs are compared to a PLCC2 LED.
