2016 Prius 3 with ATOTO Carpl

Prius 3 – ATP – Non-JBL



With screen off

Home Screen

Original Radio Part Number: 86100-47560
New Radio: ATOTO F7G110XE

Expectations/Wants going in: Retain steering wheel controls, wireless carplay (did not test android auto), reverse camera, retain FM radio. Didn’t care about extra functions/customizations from old radio, I had used Carista before to make the other changes. Knew I’d lose the radio/navigation functions on MFD display next to speedometer. Also not a huge audiophile, so better sound was not necessarily goal (but it seems to sound better?)

I had been looking at the Teyes CC3 for over a year, but really just wanted a no frills wireless carplay compatible headset. I see that atoto makes a P8 screen only carplay which seems interesting.

Install:

Mostly self explanatory for the easy connections, you match up the connections from the various harnesses (12v, Audio Channels) Harder ones are reverse camera/steering wheel controls/radio. I did solder about 90% of the connections, but ended up using wago wire level nuts to diagnose the other wires.

In hindsight, wish I went with something like this AutoHarnessHouse, that did most of the work for you.

Items of note from ATOTO (could apply to other headunits) specifically:

Power antenna blue cable from Metra 40-LX1761 goes to the harness from the ATOTO/Head unit NOT the metra harness that connects to car harness (also, had gotten lazy and tried to use butt splice, but got static, ended up using WAGO wire level to make better connection, so if you get static, it may be because radio antenna isn’t getting power)

Reverse Camera: 2016 Prius and likely other 4th gen need 6V for camera, reverse harness linked above works, 12v should be connected to ACC (ignition) the stepdown goes to “6v supply” on reverse harness, reverse signal trigger wire from ATOTO unit goes to Steering wheel AX-TOY28SWC harness (green purple)



Steering wheel controls: This was the most trouble. I went in thinking the AXXESS would be help, but I ended up not needing it (just the AX-TOY28SWC Harness), the ATOTO is smart enough to learn the resistive presses from steering wheel controls. I watched this video that gave inspiration to try bare wires

From the AX-TOY28SWC harness, I snipped the two wires that would have gone into the ASWC-1 Yellow/Green goes to Steering wheel Key + on, Green/Black goes to Steering Wheel Key#. (see pic just above)

I choose to map all the buttons on the left side to their default on the steering pad (vol + = vol +) EXCEPT I changed phone hook on to play/pause since I would be using Siri to initiate calls, so didn't need it and it didn't seem to work anyways. All buttons seem fine, may change mode to something else, but works!

AXXESS ASWC-1 issues more in detail: The axxess seemed to recognize the Prius fine based on the status LED on AXXESS, but would not work with ATOTO key registration, I could register about 3-5 steering wheel controls) and then it would reset itself, first day I had it installed, I had volume control and siri key working, but couldn’t seek tracks or hang up calls . I checked with the AXXESS updater to make sure firmware was up to date, tried changing the radio type to Visteon B based on this post

Tried changing dual assign to off, no dice, it would let me register some, but not all

Other notes:
I think you need other connections or ground in the AX-TOY28SWC harness for the other default buttons to work (Trip, right side buttons), when I was waiting for this harness, the right side buttons for MFD didn't work which was worrying.

Likes about ATOTO

• Screen is nice, says its QLED, seems bright enough
• Carplay starts automatically, takes about 10-15 seconds from power on of car
• Some customization, can change button colors, boot logo
• USB connections allows mirrorlink of iOS phone
• Price

Limitations of ATOTO

• The F7G110XE series is “linux” based, so no extra apps or functions, can’t seem to install/uninstall/reorder apps, not too bummed out this. went for simplicity
• Some slight lag sometimes

Wants now:

Installing a better reverse camera, now that its all in HD, the old reverse camera looks BAD.

TLDR: Overall, a few days in, worth it for sub $350 total install (no labor besides my sweat and occasional swearing)

I also have some TIS docs about the radio diagram which may help, it was minimally helpful to me.

 

my 3 month review.

Still pretty happy, slight issue where on first start up and carplay, the screen will "freeze" (iOS 15.x and 16.X), a quick 2 button press home and back into carplay seems to fix it, slightly annoying, but for the price and hopefully firmware will fix it, I'm okay with it.
Still pretty much just use carplay, have used radio.

Screen is pretty glossy and reflective at times, but again, for sub $350, I'm okay with it.
