Customer Ratings & Reviews

When I purchased the JVC KW-V840BT head unit with Apple CarPlay, the salesman suggested this interface module to keep my OEM steering wheel controls. While it seemed a bit expensive, I’m glad I got it because I would have missed using them. The install was a bit tedious, but as long as you follow the instructions on the Maestro website you’ll be ok. It does require you to create an account on the Meastro website, and you have to connect the interface module to your computer to flash the vehicle specific software. You do have the option to customize the function of each steering wheel control button, but I found the default functions to be all that I needed. The Maestro website will also give you vehicle specific wiring instructions. Once installed, it has been working flawlessly.

Does exactly as advertised. Did a self install. Tried to flash the unit on a Mac system, couldn’t not get it for the life of me to flash. Had to do it on a family members PC and even that was not as seamless as some of the YouTube videos mentioned. But that’s my personal experience with it. It seemed extremely intimidating looking at all the wires at first. but the online portion has you input your vehicles info and at the end it specifically tells you what specific cables to use. Would highly recommend if you’d like to keep your steering controls not sure if the install is the same on all vehicles. Some have an rca output that can be plugged directly into the aftermarket unit and can avoid spending on this product. But for my vehicle it was needed and it works great.

Using this for the new headunit in my 2009 Subaru Forester with steering wheel controls. Reading the online instructions and watching a few YouTube videos is a MUST DO prior to installing this unit. It was a little daunting at first, but in the end it all turned out to be fairly simple. The Maestro online wiring instructions specific to your make/model of vehicle are amazing! I also enjoy the ability to custom program the remote. I would recommend this for anyone who wants to keep their existing steering wheel controls.

Over the years I have become used to my steering wheel controls. When I installed a new Pioneer system I had to purchase this adapter so I could continue using the controls. It works seamlessly and I am pleased. I only wished the sales staff would have told me I needed this. They didn't and I was surprised to find out that that my controls didn't work. I would have been covered in the initial "free" installation of my system but since I didn't know, I had to pay an installation fee to have it installed on another date.

works wonderfully. just as new no issues or glitches works perfectly. all my buttons still active. it is just like new.

Worked perfectly to make my existing steering wheel buttons work with my new stereo. Had it installed by Geek Squad and have had no problems. A+

Amazing product. Glad i purchased it. Easy to use install and program.

This little box is amazing, even though it's rather expensive and needs additional parts to make everything work it really does improve the overall usability and functionality of an older vehicle without all the belts and whistles. I now have dashboard gauges and other information not previously available through my vehicles physical dashboard! Additionally with the satellite radio antenna and additional parts I can get integrated radar right on the radio itself without having a standalone unit attached to the windshield!

Not much to say, really; the installation was quick and efficient, and the interface works flawlessly and exactly as described. I've had other car electronics installed by Best Buy's competent, polite and generally well informed technicians and they have never fallen short of my expectations. Well done, once again.

This is a must in installing a aftermarket radio in a Ford Expedition. Once I installed this the radio and steering wheel controls worked like the factory radio. You do have to flash the unit with your PC, but that was simple, fast and easy to find my vehicle. I highly recommend this product.

Great Installers Very Helpful! THIS PRODUCT Did wonders for me and my life. I'd buy a million more if i could! Don't hesitate buy now! 2 Thumbs up! Absolutely Amazing and probably the most helpful single Item I've ever purchased in my 36 years. Whoever made this thing is an absolutel Angel. I just feel bad to any competitors. Thank you for this opportunity to express my complete gratitude. I WISH I had remembered to get some pictures, so now all i have is memories, but really thats good enough for me. God bless you for sharing this product to the world. Good Day

I feel like it’s a little expensive for what it does. I installed this myself, and I’m so glad I did. I’m finally able to use my steering wheel to change the volume and stations, etc. This device definitely requires some tech knowledge. I have a 2006 Honda Element paired with a JVC 750 version stereo. Works like a charm!

I really can’t review this because I had to return it because I ended up buying the mrr instead which covers a lot more than this. This would have been great too if I didn’t want to put other things in my car. If you’re just going to install a stereo by itself and nothing else I believe this would work for you.

Initially I couldn't decide whether to retain the steering wheel controls when replacing the stereo in my car. Now I am very glad I did and believe that the extra money was well spent. It is so nice to be able to change the volume (and channel) without having to look over at the stereo. That helps me keep my eyes on the road!

Work perfectly. Installation was fast very good product

Excellent. This is the only way we could change out our radio while still having the ability to control it using the steering wheel. Also, the install techs at the Cedar Hills Best Buy are the best.

Replaced awful Toyota stock speakers and system with Kicker speakers nd Pioneer Carplay receiver. What a difference! 500% better quality sound and easy to use! just plug and play! needed this product to integrate the steering wheel controls. Works great. Glad we added this to the system so I don't have to reach over to the touch screen while driving.

Seamless work, my steering controls work just like OEM, no issues what so ever

Works as designed, good value, I would recommend to you if you need it.

This product allowed me to continue to use the factory Toyota steering wheel controls with the Pioneer head unit. Works great. No issues.
