I-BUS App - DSP-Upgrade License

With this app license upgrade* the following functions of the app are unlocked:

• control of the original DSP amplifier with memory selection, equalizer, room/echo and balance, faders and treble, bass adjustment
• only for OEM BMW DSP amplifier (Do I have DSP?)

 * An existing OBC license is required for the function. The DSP-upgrade license itself does not work.

Apart from the App (license) and the Resler Interface, no additional changes to the cabling are necessary to control the DSP.
Indications from radio manufacturers that these do not work with DSP are thus obsolete.

Here you find a list of all functions of the app

For using the application the electrical integration of a  Resler Modul and an Android device (from version 5.1) with full USB connection is required.

Please note: What do I need to use the I-BUS App?
