In the time that I’ve had my 2006 Lexus IS350, I’ve had a couple issues with the touch screen. One issue was the notorious frozen touch screen issue where the digitizer has failed. The second issue was the head unit screen going completely blank. The screen was totally black even though the car was on. This issue had a quick fix, which was to check the interior fuse box. Thankfully that took care of the issue before I had to go further with additional troubleshooting or worse, a full head unit replacement.

I’ve replaced the head unit/radio in my 2003 Toyota 4Runner countless times for various stereo upgrades, so I’ve gotten familiar with taking the trim apart to get access to the head unit. After doing it so many times, I’ve been able to get my time down to less than five minutes. I figure this tutorial would be helpful for anyone trying to remove their radio and want to get to the head unit quickly.

After upgrading the 4th generation 4Runner stock head unit with a Scion T1806 and then a T1814, I finally ended up with a T10015. In my opinion, this is the ultimate, stock-looking, head unit for the Toyota 4Runner. I realize that I could probably do a similar radio swap with a Scion T10017, which is offered on Scion vehicles in 2016+. Since I had already done most of the work on installing the adapters on the Scion T10015, it would probably require minimal work to get the newer T10017 unit working.

I finally decided to take a step up from the previous Ebay backup cameras I’ve used, to a better camera and a more refined display system. The Rydeen backup camera and Scion T10015 head unit pairs up nicely. The install was a bit complicated at times, but the seamless operation of the backup camera function makes it all worth it.

The touch screen suddenly stopped working on my Lexus IS350. After realizing a repair with a conductive pen wouldn’t work, I decided to replace the whole digitizer. At only $20 for an aftermarket one online, I thought it was a no brainer.

When upgrading the stock 4th generation 4Runner head unit, you can use other Toyota head units, aftermarket head units, or even Scion head units. Since I’m an fan of using OEM parts for upgrades, I started with a Scion T1806 and then moved on to a T1814…

The stock 4th Gen 4Runner head unit is terrible… there are so many direct-fit Scion head unit options out there for our cars. I’ve gone from the oem radio, to the T1806, to the T1814, and now looking to upgrade to the new T10015 head unit!
