The Hella Gutmann app combined with the pre-installed apps of your choice makes your tablet a fantastic
allrounder. You can diagnose and communicate, retrieve additional information from the web to your workstation, monitor your time management and much more, using just a single device. After concluding the licence agreement, you will receive the Bluetooth VCI which mega macs ONE uses to communicate with the vehicle. You will also be able to download Hella Gutmann 'mega macs ONE‘ app. Once installed on the tablet, you can use it on an unlimited basis. All the diagnostic functions available on the mega macs ONE are the same as those on conventional mega macs diagnostic tools. These range from displaying the OBD interface in the vehicle, to reading/deleting trouble codes, resetting service intervals, parameter depictions (up to 16 at the same time), basic settings and actuator tests.

mega macs ONE also offers up-to-date customisation options, such as landscape and portrait screen mode, changing both alarm duration when leaving the VCI wireless range and recording duration of measured values. As is the case with our conventional mega macs diagnostic devices, you also have the option
of booking regular updates and services for mega macs ONE and contacting the Technical Help Line for assistance with diagnostic tasks.
