So I have finally (mostly) completed this swap. I have searched the forums and found some good information but found myself with a lot of questions that needed to be answered. Instead of hijacking another thread, I decided to start my own write up. My setup is a 2010 SR5 with the basic stereo head unit. I’ve been wanting to upgrade for a long time but kept holding back because I either didn’t have the info I needed, or I couldn’t find the right deal on an Entune. I really like the factory look and wanted something that would integrate well. A hat tip to these posts that got me most of the way there.

I’ve spent hours researching connectors, wiring diagrams, photos, compatible parts etc. and have come up with this list of factory and aftermarket parts. This, I believe, is the least expensive route after comparing everything and options.

Listed for reference, but I didn’t buy this part since I don’t use sat radio.

The thing that was throwing me for biggest loop was understanding what each plug on the back of the Entune was for. Below is a photo that gives a high level understanding.



After studying a wiring diagram, I could verify what parts to look for. I think the GPS antenna was the biggest “leap of faith” on this project. Obviously spending $200 - $300 on a factory antenna was not going to cut it, however, there isn’t one on the market with that connector plug. I even tried to search for just the connector on the Toyota parts site, but I don’t think Toyota sells it. I spent a ton of time researching GPS antennas and connectors and finally decided to try the one in the link above and it fits perfectly! Trust me, there’s no falling out with this thing, it’s on there. That custom Toyota connector is a joke. FYI, the radio connectors (nav, sat and AM/FM)… (maybe this was obvious to some, but definitely not me) for the record, they’re all female SMB connections.




To place the GPS antenna, remove the clock in the dash (two screws, very obvious), it’ll expose the area where the stock GPS antenna would go (between the vents). I literally just made sure it was right side up and placed it in there. The GPS signal picked up within a couple mins and works perfectly!

Everything is straight plug and play (except the backup camera). From what I can tell, nav, apps, HD radio, Bluetooth (phone and audio), and the steering wheel controls also work.

In order to activate the premium apps, search for a 4Runner online for sale or whatever with premium Entune and grab the VIN. You’ll need this for verification/activation.

Next steps…

1) The backup camera is going to be a bit of a hack, but I know it’ll work out fine since the wiring diagrams have the wires labeled, and the harness seems to have all the connections I’d ever need for it. I need to purchase some wire and make the runs. Admittedly, I don’t need this since my mirror provides the backup camera, but I want to see this work. There are write ups to access the wires, etc. While in here, I plan to do the rearview on demand hack.

2) Replace the LEDs with color matching ones, either new or from my old head unit. I took apart my old radio, these suckers are small. When I tried to search for them online, they appear to be less than 1mm wide total. Currently looking to desoldering techniques.





3) Painting or replacing the silver plastic in the rest of the 4Runner to match the black.

Hope this helps anyone looking to do the same! I’ll post updates as they come along, but with a new baby, it’s a little tough to find the extra time

Nice write up!

Man I wish I had this info a week ago, before I went with the Maestro and new HU. Thank you for this information, I'll be selling my 510140 head unit soon.

Just curious did the party mode button still work or was it disabled after the swap?

So it does, but it’s not as obvious of a shift as before. Kind of hard to explain.

But I can say in general, this head unit sounds much better than the old one, maybe it’s the new shiny factor, but to me the sound quality has gone up overall

When I temporarily installed the HU since CD only worked (due to lack of research on my end, until today!) I noticed it sounded much clearer. The following week I added 4 new MB Quart XK1-116 in the rear doors and hatch and it was booming. I did the Subaru Kicker front dash replacement and left the front stock 6x9 for the decent mid bass.

Hey i followed your guide. Did you ever have any issues with the volume button not working? And only working during phone calls?

We’re you able to get the back up camera working? I did the swap cause the screen on my 2012 cracked so I purchase a 2016 Entune unit installed it but the back up camera and Entune apps don’t work the only thing working is the navigation and and am,fm radio if you could help with the camera issue I’ll really appreciate it
Thanks

Hey, I never had any problems with the controls or volume. Everything worked right away... I could only imagine that there is a connection issue with the wiring harnesses. Do you have a multimeter to test continuity on the buttons and the harness?

I still have not done the backup camera mod. My rearview mirror has backup in it so it was never a priority to update. I was able to activate the apps by looking up a VIN online for a 4runner that came with this as IRM equipment

Sorry to revive this, but were you able to figure out what that empty plug is for in the back of the oem radio. You listed on the pic you weren't sure but old one had it. Mine is empty and wanted to make sure I wasn't missing any connections when I was back there. Thanks!

I never discovered what that was used for and haven’t had any issues. FYI, l am still running the same setup since I published this article. Too many other projects and kiddos running around to get to the remaining items. Stereo is way better than stock and I’m living with the color mismatch haha

Thanks to the OP for this thread and the detailed info. I know this thread is old but I have completed the retrofit too, with some differences, as well as getting the backup camera to work. I have a 2012 TE that came with the non-jbl nav unit. Originally, I replaced my factory HU with the Cartrimhome T9 in early 2020. It was great for about a year and a half until the capacitive buttons stopped working as well weird stuff like the youtube app wouldn't output sound, radio stations stopped coming in, etc. I pretty much just started using it for Android Auto.

TRD Jon on YouTube made a video on installing the Beat-Sonic TAV-CB2 S-Connect Interface in his 2019 model which let him use CarPlay/AA on his factory HU. Seemed like a good way to get a stock look, so I decided to go that route. However, a newer HU had to be installed since the Beat-Sonic unit only supports the 14-19 models. Which lead me to this excellent retrofit thread.

These are the items that I purchased to make this work:
- Silver 2017 Nav HU that I purchased for $150 on ebay
- 2017 climate control unit purchased for $75 on ebay from salvage vehicle (not needed, but helps with the light mis-match issue)
- Beat-Sonic TAV-CB2 S-Connect Interface: Beat-Sonic Apple Carplay and Android Auto for 2014-2019 Toyota models with Entune 2.0 and Entune 2.5
- GPS: Amazon.com: DHT Electronics External GPS Antenna with SMB Female for Verizon Samsung 3G Network Extender : Electronics
- 2012 backup camera wiring harness adapter: Amazon.com: AXXESS Toyota Back-Up Camera Retain/Add-On 2012-2015 : Electronics
- 2014-2019 backup camera wiring harness adapter: Amazon.com: AXXESS Toyota 2013-2016 Back-Up Camera Retain/Add-On : Electronics
- XM Satelite adapter: Discount Car Stereo > Antennas and cables > XMM-TOY Toyota, Subaru, Mazda factory XM antenna retention cable

I was able to get everything working except for XM radio, which seems like it should work but says no signal. I'm not really a subscriber, so not a big deal. The new HU has blue lights instead the orange lights that is present in my model year, so I offset that a little by also purchasing a salvage climate control unit from a newer model with blue lights.

With the Beat-Sonic unit I'm able to get Android Auto/Carplay.

The last pic shows the backup camera working. It took some effort to get this working: To overcome the two different harness plugs, I used the female end of the purchased 2012 backup camera harness and spliced it to the male end of the 2014-2019 backup camera harness. I didn't look at any diagrams I just matched the wires by color. Doing this essentially creates an adapter harness cable. In the end, all the wires will be spliced together with the exception of one black and one yellow wire which were extra and meant for connecting to power and ground if needed. There is also the yellow video composite cables that aren't needed. I taped all of these off so they don't cause an interference. Definitely had my doubts, but it works lol.

I'll also state that if I can find a salvage HU for cheap from a 2020 or newer model I will try to retrofit it because the entune 2.0 HU screens kinda sucks.

Here's some photos showing stock entune, Android Auto, and the backup camera in action.

I have a 2012 limited with in dash backup camera non-JBL. I am trying to splice the exact same harnesses for the back-up camera you used. I found them both @ best buy.

One with 16 pin and the other from 2014 and above has 24 pins. The black, yellow and video cables (total 4 wires), now I am down to 20 wires. I am curious to know what have you done with the reminder 4 ?

how is that beat sonic unit working for you? I want to add CarPlay to my 4Runner...
