excellent, easy to hook up and works without any hiccups

Pros: Works, easy to install

Cons: none

Good adapter?

John from Abilene, TX on 7/22/2017

2014 Toyota Corolla
Crutchfield Customer Review (What's this?)

Easy to use but, the instructions weren't the best. My radio had the antenna hook up and I don't have a motorized antenna so I wasn't sure if I needed to connect the blue wire. I connected the blue wire just in case and everything seems to work fine.

Pros: Fits nicely

Cons: Not enough information

Works perfectly

Peter from Maryland on 7/19/2017

2014 Toyota Highlander
Crutchfield Customer Review (What's this?)

Perfect. One thing to keep in mind, though. When the instructions state "connect the blue wire for power antennas", it does not mean the old school type that raise and lower when you turn on the radio. It means "powered antennas". The antenna in my vehicle is built into the glass, and has an amplifier. I had no way to know that, except that the radio had no reception. Until I connected the blue wire!

Crutchfield Customer Review (What's this?)

Worked perfect in my 2017 Camry with factory Entune Plus and JBL system. Make sure to connect your head units +12 antenna control lead to this adapter's blue lead to provide much better signal. Toyota must employ an RF amplifier somewhere.

Pros: Perfect for the application.

Cons: Don't forget to connect you antenna control lead to this adapter's blue lead.

Pros: Smooth install

Cons: Did not need the antena power wire but I'm glad it was included.

Works, but instructions are incorrect. In my scion FR-S the blue power wire MUST be hooked up for it to work.

Pros: Fast Simple and works

2010 Lexus IS250C
Crutchfield Customer Review (What's this?)

Adapted well between my cars factory antenna(s) and new radio, though documentation was limited. Which adaptor should I use?

Pros: Exact fit between factory car antenna(s) & new radio.

Cons: No info to help choose between the two provided adaptors. Both would fit but found out one is for cars like mine with separate AM & FM antennae.

Enhanced Radio Reception

Rocco from Escondido, CA on 2/27/2017

Crutchfield Customer Review (What's this?)

I'm sure the new head unit has something to do with the much better radio reception from the stock head unit, however, this adapter connects to the remote power lead and activates the stock antenna booster. It works perfectly, and radio reception is much improved.

Pros: Much better radio reception

Cons: none

2014 Subaru BRZ
Crutchfield Customer Review (What's this?)

Works as it should, although the wiring is set up improperly for a Subaru BRZ. This is the Toyota powered antenna wiring setup, which works on the Scion FR-S, but you don't get power to the antenna via this blue wire for Subaru. You'll use the blue wire on the 10 pin harness. If you have a BRZ, search online for proper instructions.

Pros: Works well, inexpensive

Cons: Generic wiring for BRZ/FR-S, should have separate versions instead

Easy to install plug and play

Ross from San Antonio, TX on 12/13/2016

2016 Toyota 4Runner
Crutchfield Customer Review (What's this?)

What's that blue wire for? This adapter doesn't come with instructions. The google-machine tells me it's a "power" cable. My 2016 Toyota 4Runner SR5 doesn't have an antenna that goes up and down, so I don't need this blue wire hooked-up... right? Wrong! If you don't connect the blue wire to +12V you'll get like 3 radio stations. I connected the blue wire to my Kenwood's blue wire (labeled "power ant" or something like that). Now I get like a billion radio stations. Maybe "power antenna" in this context means "needs power to improve signal strength or reception power". Easy to hook-up, but I had to take the dash apart a 2nd times to get it hooked up correctly.

Fits great easy to install

Pros: Perfect fit

Cons: No instructions about the blue wire so I did research on the net and everyone says to hook it up 2a acc power which works also scoshse offers a connecter for our backup cameras that are 6 volts too bad for the price plus shipping but it duz work and only 2 wire hookup

2016 Toyota RAV4
Crutchfield Customer Review (What's this?)

Just connect the blue wire even if you don't have a powered antenna. The blue wire is used to power diversity amps in some vehicles, including mine. It made the difference of barely picking up 3 channels to picking up everything and then more.

Pros: Easy to install, plug and play...

Cons: Absolutely nothing

Great!

Crutchfield Customer Review (What's this?)

easy to set up and wire.

Pros: easy to set up and wire

Cons: when I first installed it there was no way to secure it in the back of my Pioneer AppRadio 4- so it slid out a bit and I had static on my AM/FM- but I had to go back in for something else so I pushed it back in and now have no static.

Antenna adapter for a Toyota amplified car antenna

Cristino R. from Bayamón, PR on 8/14/2014

Crutchfield Customer Review (What's this?)

Adapter to connect your Toyota amplified antenna to a more common RCA plug equipped aftermarket radio. I connected the electric wire to my Parrot Asteroid Smart's Power Antenna wire. Works like a charm! If your aftermarket radio does not provide a switched output, you could use any +12v that is on on accessory.

Pros: Plug and play.

Cons: None

This adapter harness, along with the Metra 40-LX21 Antenna Adapter harness, worked interfacing my JVC HD radio receiver to my stock radio. When using both adapter harnesses, don't forget to connect the two blue wires together. I used a small wire nut for that.

There is a plug from the antenna that looks like the pointy metal end coming off the white plug. Plug that into the white plug and the one on the adapter goes into the radio.
