MDD on M800 CAN0

[Paragon]

I have been connecting a MDD to a M800 as a auxiliary display on a rally car. Ver 1.14 and the latest M800 firmware.

It appears that it will only receive data on Can 0 from the M800, is this correct ?

Should the firmware in the MDD be upgraded ?

I would like to display 2 users channels on the MDD. This is possible in tuner mode, can it be done in user mode ?
