    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)

    5.0 out of 5 stars Perfect companion for my Ford Transit Connect
    Reviewed in the United States on June 27, 2022
    My Ford Transit Connect needed a re-vamp so I bought a JVC KW-Z1000W 10" floating display unit and bought this Maestro RR unit to retain my steering wheel control. A whole lot of research was required but I gotta say the instruction that the software from iDataLink is superb and very straight forward. Here's some of the highlights of installing this guy for my Ford.
    1. Steering wheel control retained - not only I'm able to control volume, skip and rewind buttons, I'm able to use my SYNC talk button as a SIRI trigger for Apple CarPlay.
    2. Vehicle error notifications displayed in codes - this might depend whether your stereo supports this feature or not, but normally when an engine light comes on you'll have to take your car to the dealership to figure out what the issue is. Fortunately, RR is able to translate the language and display to your stereo screen.
    3. Rear view camera automatic trigger - if your stereo unit has camera support, you no longer have to wire your camera to the rear light to trigger the camera - somehow RR is smart enough to signal to the stereo that the car is in Reverse and shows the rear camera right away.
    4. Vehicle information - this is also dependent on your stereo but RR is able to communicate to your stereo about your car's status which also shows car voltage and tire pressure. It also shows basic information you see on your dashboard but that might not be necessary.

    Overall, I could not be happier to retain all the original function and make this work like this. Wiring is simple enough as long as you follow the wiring diagrams depending on your car model. Have fun!
