The new m.unit blue’s one particular advantage over the m.unit v.2 is that it incorporates Bluetooth® LE technology. This means the m.unit blue can be connected to your smartphone using the m.ride App.


This feature is truly unique for motorbike accessories. The m.ride App manages the entire setup and alarm system. Fault diagnostics can also be performed during operation and without having to remove the m.unit.
