Audi Music Interface (AMI), Mercedes Media Interface and Volkswagen Media-in Multimedia Port (MDI)
These 3 iPhone / iPod systems are the most common and known. Basically they do the same job. They integrate iPods into the entertainment system (head unit) of a car and allows to stream music directly from them via a cable connected to the iPod device.
Moreover, it has a broad functionality. It allows user to select albums, artists, songs and genres with the head unit keypads or multi-function steering wheel and show this information on the car’s display (if applicable). In some configurations can be found a USB port next to the iPod/iPhone 30-pin cable. This port is used to read multimedia files from USB data storage device.
These systems are usually located in the center console or glove box (see pictures below).
Initially these systems where designed for iPods thinking that you will be listening to the music only. None thought that a mobile phone will become an all in one device and replace the use of iPods. For that reason car drivers face and issue when they connect their phone to one of the media interface the phone must be kept in the glove box or center console making almost impossible to answer phone calls. Also with so many music applications like Pandora and Spotify, switching apps to play music is imposible having the iPhone located in the glove box or having to open a compartment in the centre console . What if you want to use your phone as as navigation device, just imagine having to reach your phone , set a new route and plug the device back inside the glove gox plus you wont be able to watch the phone screen for the map. Finally who has time to connect / disconnect a phone every time they get in to / out of a car?
Don’t foget the new iPods and iPhone 5 and iPhone 6, have a new connector called lightning , these new devices won’t fit into the 30 pin connection.
How to stream music and sound to these audio/media interfaces without using the 30 pin connection (wirelessly) ?
There is a solution now in the market called Viseeo Tune2air WMA3000A that plugs in into the 30 pin iPod/iPhone interface. Tune2air WMA1000 has builtin bluetooth so will stream the music from your iPod, iPhone or iPad device via bluetooth to the media interface and you will be able to select song, using the unit keypad, same way as if the device was pluged in directly.
BMW USB / AUX-IN iPod integration system
The only difference from the previous 3 audio/media interfaces is that BMW used a different connection. The power to the music device is streamed through USB port and the sound is received through AUX-in port. USB alone does not function with media devices such as iPod or iPhone.
A new device Viseeo Tune2air WMA3000B to support the BMW / AUX-IN media integration has been released and sold by Smart World Company.
