Review: Fantastic (with minimal limitations) in Mk2 Audi TT - Very impressed with this module. This review is to give specifics of what does and does not work in this specific vehicle and hardware combo. Vehicle is a 2011 Audi TT-S (Mk2, 8J). Radio is Pioneer AVIC-W8500NEX. This module does not let you retain the factory amp, which my car had. There are at least 3 possible types of factory systems for this car: Concert radio without factory amplifier, RNS-E radio with factory amplifier, and Bose radio with factory Bose amplifier. I had the RNS-E with amp combo, so I had to manually bypass the factory amp (in the driver's side hatch compartment). Firmware setup was kind of difficult because you need Internet Explorer (not Edge, Chrome, Safari, etc.) and there are some specific Java and such updates that you need. During setup, you get to decide what your steering wheel buttons do. There are separate functions for press and hold for when you press each scroll wheel in and for the voice button. There are also ways to set a function for when you hold scroll up or hold scroll down, which doesn't really make sense, so I didn't set anything for those. Also, you can't program anything to the Mode button. I was able to make volume, seek, mute, source change, call answer, and Siri all work. Scrolling the volume is actually just as responsive as it is from the factory, except when you're on the gauge display, when there's a slight lag. Song and call information does appropriately display on the factory gauge cluster in the top 1/3 segment. HOWEVER, you have to set it to MFD type 2 in the settings menu on the radio, AND it doesn't scroll. The top line says the source type for awhile after changing it, then changes to the song title. The second line shows the artist, then changes to the album name. This all works regardless of the source type, interestingly including wireless CarPlay, which I didn't expect. The gauge display screen has a ton of options for gauges to show, and it can show up to 5 at a time. There's about a half second lag, but it's still very cool. I forget all of the options as you have to configure them when you set the firmware up, but there are two presets that I set as you can see in the pictures. You can have it record peak values and set indicator lights for when any parameters go out of range. The second screen that can be displayed isn't particularly useful. The door open indicators, battery voltage, and check engine light tool all work, but tire pressure analysis doesn't work on mine (it may on other trim/option levels). I had a check engine light and was able to see the specific code and clear it with ease. The section for climate control doesn't work (probably doesn't work on any TT's), and the parking sensor section doesn't work, but may if you have that option on your car. The unit also does some other things like allowing you to retain your factory Bluetooth functionality (so you can use the factory microphone and vehicle Bluetooth connection), but I preferred to use the Pioneer Bluetooth instead. The unit also provides +12V ignition, VSS, parking brake, and reverse light wires during installation, which drastically simplify things. Overall, I couldn't be more pleased with this unit. Many sites say they don't recommend replacing the radio in this car, but I see no detriment at this point as long as you know how to bypass the factory amp and use the Maestro module (VW1 harness is also "required" for use...I'm sure you could hardwire it somehow, but it GREATLY simplifies the installation...and there's a ton of space behind the radio to put modules, wires, harnesses, etc, FYI)
Review: Features specific to your vehicle. Amazing unit! - 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.

*by M***T on June 20, 2019*

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.
