From the dquid webpage
In July 2012, with RE:Lab and Piaggio, we released the Piaggio Multimedia Platform, our technological solution targeted for the 2-Wheels’ world.
According to DQuid architecture, the former system was comprised of an additional control unit directly integrated into the vehicle and an APP which can be downloaded for free from the Apple Store.
With the Bluetooth® connection, the hardware unit communicates important driving features to the bikers’ smartphone : Additional trip computer, Warning system and Service information; Satnav function.
After one year, the system has been adapted for two other Piaggio’s vehicles:
Aprilia Caponord 1200 and Piaggio Vespa 946. In these new cases, there was no need to change APIs to develop mobile applications. The DQuid development framework permitted to interact with various models of differents brand without problem due to differences between the protocol language implemented inside the objects.
