I’m pretty sure that will only work with 2020-2021 due to the changes with the plugs on the Entune 3.0 head units.

 

@TRDFerguson is correct. HRN-AR-TO3 is for earlier Entune headunits (at least that’s the one I used)

 

According to Crutchfield it says 2018-up.

 

That just means it fits select Toyota vehicles. I just punched in my 2018 to check, and…

 

I believe Entune 3.0 was launched in some 2018 models like the Corolla and some other cars. 2018 and 2019 was a crapshoot for compatibility. 2020+ started to standardize a little more.

 

If the harness does not fit your vehicle I can sell the Maestro RR separately.

 

I think there is some confusing information being presented here.
My understanding is the XXX-RR-XXX harnesses are for radio replacement , while XXX-AR-XXX harnesses for amplifier addition or replacement.

The best solution is for anyone interested to just go to the website at https://www.idatalinkmaestro.com/en, enter your vehicle and answer a few questions, it will tell you if the cable will work for you.

If not consider the offer to buy just the RR.

 

Thank you for providing this. You are correct. This harness was used when I replaced my stock radio with an aftermarket. Only selling it because I installed my stock stereo again.

I have a 2018 and use the TO2 harness, not TO3. The “2018-up” is talking about Camrys, etc. that got the Entune 3.0 units.
