Maestro ADS-MRR Universal Radio Replacement and Steering Wheel Interface

I have been installing aftermarket stereos in my vehicles since I started driving in the 80s. It has been a few years since I have done one, and I was amazed at how far the technology has come with units like this Maestro ADS-MRR. I was able to program it specifically for my older truck I just purchased - a 2014 F-150 with a tiny, stock 4.3" screen. During programming, it showed a diagram of my steering wheel buttons as I chose what function I wanted to use with each button - very specific and VERY helpful! There was no guesswork. One word of caution - I used a MicroUSB cable I already had connected to my computer and it did not power on or cause the computer to recognize that a new USB device had been connected. I knew the cable was good, so I thought maybe the unit was bad or needed something else done. I tried a different cable and had the same result. When I used the cable that came with the unit, it lit up and connected just fine. I don't know why - it is just another MicroUSB cable, but for some reason, my others did not work. The one supplied is a little beefier, so maybe that was it. The unit works great. Setup was not difficult. The instructions are not as thorough or understandable as the video they had for my vehicle on their website. Using the two together helped make the installation easier. All in all, I highly recommend this unit. I am thoroughly pleased with the result and have a fantastic stereo setup in an older truck.

This is the one of the coolest devices I've ever seen. It talks to your car and passes the information it gets through to the Head Unit, and it works really well. The software for it is easy to use, the guides on installing it make sense, and the company even has a support forum where you can talk to their engineers to get help if you need it. Be sure to buy the right harness for your car(you can check their website to see which one you need), and follow the wiring diagram from the website exactly. It does include some cables, but since I had the GM5+ harness they weren't needed. My only gripe is that some of the connectors on the Maestro didn't fit all the way in at first, so they may want to do a little QA on those- I just had to mess with them a bit until they were snug. This does allow you to see all the info about your car on the head unit - tire pressure, fuel level, diag codes, Transmission Fluid Temp, and tons of other stuff. It also let's you keep your steering wheel controls, and their software let's you customize what each button does. The unit is also small enough to fit under the head unit or in the dash, so you don't have to worry about finding room for it. Overall this is a cool product, and you can tell a lot of time and money went into developing it. Definitely worth buying if you're upgrading your radio.

This interface, along with the correct harnesses, allowed me to keep all factory features on my 2008 Silverado 2500HD LTZ. It must be flashed or programmed to your specific vehicle and factory options using a computer. The website does a good job guiding you through the setup by showing you options with drop-down menus specific to your vehicle and all the different available factory options. Uses actual pictures of factory steering wheels to make sure you select the correct options. It also asks for the specific model of your aftermaket head unit and has actual pictures of each unit for reference. Setup only takes a few minutes if you know what options your vehicle comes with. The one and only thing i didn't like about this interface is that it has connectors on opposite sides and makes for a slightly less neat installation. I moved the factory harnesses around to help make the installation a little neater and less bulky. There was one harness that i wasn't sure about, so i called the manufacturer and their customer service/tech support was quick and outstanding. i wasn't on hold at all. just called pressed a number for tech support and someone with perfect english was on the line within a few seconds. i wasn't asked for any information regarding purchase date, purchase location, or serial numbers of any sort. just asked for vehicle and head unit information and answered all of my questions within about 4 minutes. The person on the line even offered to give me a walk-though of my head unit features. When used with the correct harnesses this interface allows you to keep all of your factory features and even adds some extras (Gages that read vehicle info from OBDII port if your head unit supports it). Please note that at least a little bit of technical experience helps with the installation. If you have never installed an aftermarket head unit before, professional installation may be required.

This is my second Maestro device. The first had an issue where some relay would randomly reboot my radio once per drive and it would stop displaying track info on the car's information screen, and occasionally it would also disable the steering wheel controls. Not great, but it worked. That radio I was using eventually burned out an internal capacitor and took the Maestro with it, so I bought a replacement. This go around I chose Maestro again hoping I just got a bad unit last go around, same car, same radio manufacturer. This radio has a speed input for the car, whereas the previous one didn't, and here's why that's important - when Car Play is enabled I can hear the speed input ticking from the car wheel sensor through the Maestro. Very faint, but with low volume settings it's very much there. Also, it will occasionally just crash Car Play. Once a month maybe, but I'll check my radio screen for map info and it's gone and replaced with message that the Car Play function isn't available due to a Maestro error. Press "OK", and then Car Play, and it works again. When it works, it works well. Annoying issues for how much this unit costs, though.

Not happy. It was not advertised as a used product. It arrived with half of the cables missing.

Great product and great Support. Hooked this up with DMX1037S and it goes along very well. The support personals via the 12voltdata forum are excellent. They are fast to attend to the queries and helps. Easy to install as long as you follow their installations and have a bit of knowledge on the radio wires.

The factory stereo in my 2009 Ford Escape was very closely integrated with the medium speed CAN bus. There was no ignition +12V or illumination wires present in the connector, as both those signals were sent serially over the bus. The Sync (APIM) module, the Satellite Radio Receiver (SDARS) module, and the auxiliary display above the vents (FDIM module) are all only controllable via this bus. I was extremely pleased to find that this neat little product was capable of retaining ALL of those network functions with my new aftermarket radio. It provides the necessary switched 12V outputs for accessory and illumination, it can retain full Sync functionality (personally I have it disabled), full factory satellite radio (including channel names, artist/title of tracks, presets, etc), and it even displays the current time and date on the auxiliary display (time synced from the aftermarket radio, which itself syncs from GPS). It also provides a bunch of other useful feature, such as VSS (vehicle speed sensor) pulsed output, reverse lamp output, and parking brake output. The built in steering wheel control interface also works great. I love that you can flash the firmware and settings easily over USB, and all you need to do is create a free account. I found a minor bug/limitation with my specific aftermarket radio, where the auxiliary time display takes up to 60 seconds to "refresh". This means upon startup it spends up to 60 seconds displaying a completely wrong time/date. I contacted idatalink support, and within a day they had figured out what was going on, and they'll be releasing a patch to work around this limitation in the near future. If you want to upgrade your stereo, but your factory radio is CAN bus dependent, I highly recommend this product! I don't think any other competing product comes close to this level of integration (especially since most aftermarket radios have built in support for this interface).

Una maravilla de integrador. Funciona a la perfección, aunque si requiere dedicarle un buen rato, y el cableado tambien requiere de atencion, pero bien vale la pena el esfuerzo

I have a newer Civic with Honda's premium audio system with factory amp and subwoofer, and integrating those into a system with an aftermarket deck is pretty much impossible without something like this. That isn't the only benefit, you can also retain your steering wheel controls for your stereo, and if you have a compatible stereo, integrate things like tire pressure sensors and OBDII code reading INTO YOUR STEREO. You can also have your installer set custom functions for your steering wheel controls if you choose, and a bunch of other cool features. Be aware, along with this module, you will need the applicable Maestro wiring harness to go with it, which in my case was an additional $50, but in my opinion it was worth it in order to keep the factory components and retain my steering wheel controls. The other features are icing on the cake. Worth the cost.
