Perfect fit

Dave from Chapel Hill, NC on 3/1/2017

2009 Toyota Prius
Crutchfield Customer Review (What's this?)

Corrected operation of compartment door that did not work right with the way the previous aftermarket radio was installed.

Pros: Makes installation of aftermarket radio look like it was there originally. Plastic mounting brackets give a better fit than the original metal brackets.

Cons: None

Looks good, needed a little trimming

Crutchfield Customer Review (What's this?)

Installed in a 2007 Prius. It looks good with the rest of the dash. I had to cut off the lip on the tray for the bezel to fit in properly on the dash. Other than that, it worked well. The plastic brackets seem sturdy enough once everything is in place.

Pros: Bezel looks good, all hardware included

Cons: Tray didn't fit until modified

Perfect Fit!

Great fit and function, and the best price online, with awesome shipping.

Pros: -Fit perfectly and securely Price Ease of use Matched car interior

Cons: Had to purchase additional mounting hardware. ($3.00)

Did not see the resistor in pack, was not marked or packaged visabilit

Crutchfield Customer Review (What's this?)

The fact that the resistor was not seen or any instructions relating to installation caused a major redo of installation and an over night rental of car.


Cons: Resistor needs to be flagged and identified better.

Crutchfield Customer Review (What's this?)

The kit worked well for me. As others have said, the construction is somewhat flimsy, and it looks as if I could have simply reused the original Prius metal brackets. I wish Crutchfield had explained that there is another installation option that doesn't require this kit. You can install the new single-DIN radio in the cubbyhole under the stock radio and leave the stock radio in place (inactivated). Some people call this a "stealth install" because from the outside, the car will look as if it has just the stock radio, reducing the risk of theft.

Pros: Fit perfectly as long as I left the manufacturer trim off the radio.

Cons: The 68 Ohm resistor is crucial and hard to install. I had to solder in the car - something all the other Metra harnesses are designed to avoid. Isn't it possible to spend $0.10 in plastic to build an adapter plug that contains this resistor? In my case, it could have been integrated into the harness for the AXXESS-SW1 steering wheel control adapter that connects to the same connector.

missing parts, bad fit, so-so quality

heyzarling from Hustisford, WI on 8/11/2014

2005 Toyota Prius
Crutchfield Customer Review (What's this?)

If there were a 1.5 star I'd choose it; 2 would be too generous. My unopened bag did not contain some pretty critical parts; was supposed to come with a 68 ohm resistor, which was necessary to retain really all of the display functions on my Toyota Prius (you have to solder this in so the car 'sees' resistance similar to factory radio, cause if it doesn't, you lose climate controls, other monitor/display info...which I did lose). So a trip to the store to buy 5 of them, only a couple bucks, but time and gas to get there, then pull the dash apart again to install. I'll assume that whatever little bag was missing would have also included dash clips, and also screws to hold the spacer/compartment gadget. I had a couple screws that fit okay. The brackets themselves...very flexible, pretty flimsy plastic, but holes lined up and they worked fine. However, the little dash piece that shows is not at all a good fit on this 2005, anyway. When I have more time maybe I'll try and carefully shave it to make it fit better. Overall, for the price, I would absolutely expect everything to be included, and really to fit perfectly. This can't be more than $5 in stuff, including what was missing.

Pros: Made it work.

Cons: Missing parts. Iffy quality. Exposed dash piece fits poorly.

Crutchfield response on 8/13/2014 After seeing this review, we are examining these kits to make sure they really do include all the parts the manufacturer says they do. The one we looked at when we first started carrying them certainly contained all the pieces. Hopefully this was just the bad apple in the barrel of kits. If any of our current stock is also missing the hardware, then we'll contact Metra to get those items.

2007 prius single den Metra kit

vuong from Philadelphia, PA on 4/26/2014

2007 Toyota Prius
Crutchfield Customer Review (What's this?)

It came with everything I needed, no hidden secondary, sold separately parts. The factory bracket that holds the radio and den is metal, Metra was a flimsy plastic. I'm actually surpassed it didn't break. The facade wasn't a perfect fit. I used a dremel to shave off a large chunk. Even after that it still wasn't a perfect fit. At the end, there was a cm gap from the Metra facade and the upper middle console.

Pros: Color looks close to factory. Complete kit. Decent price. Simple install.

Cons: Flimsy bracket. Not a perfect fit, requires shaving.

Decent Kit

Busmonkey from Southern MD on 3/21/2014

Crutchfield Customer Review (What's this?)

Good kit, but had some fitment issues. I had to cut most of the flange off the pocket to make it fit, but the end result is good. Material is good, not great, and there is a very minor finish problem with my kit--not a big deal, but certainly not perfect. The Prius instrument panel was designed to be sleek and smooth; installing an aftermarket unit is not going to work with that look, unless you go with the stealth install, which I didn't. This kit will get you pretty close.

Pros: Easy to install, decent quality and looks.

Cons: Overall quality is decent, but probably doesn't match your car's OEM or the quality of your head unit.

Overview: The Metra 99-8240B is a vehicle-specific installation kit for installing an aftermarket stereo into select 2004-2009 Toyota Prius vehicles.

Note: When you replace the factory radio, the factory navigation (if present) will still work, but you'll lose the voice guidance system.

Climate Control Retention: In order to retain the vehicle's factory climate controls, the included 68Ω resistor should be installed between two wires on the factory harness. Installing the resistor will also retain factory navigation, if equipped. The resistor should be soldered to the factory wires and covered with heat-shrink tubing or electrical tape. The instructions for this modification can be found in the 99-8240B Owner's Manual.
