Dension Gateway 500 instead of HARMAN/BECKER AUU USB MOST

[bosiarz]

Hi,
I have in DB9 HARMAN/BECKER AUU USB MOST module with iPOD and USB interfaces.

I would like to change it for Dension Gateway 500 to get also AUX input. Is it possible to connect it directly in the place of the old module in the meaning of the MOST wires or it is neccessary to connect with CDC. What at this situation with a free MOST socket? Isn't necessary to close a light loop?

I have module like on the photo.

I already put Dension in the place of the Fomoco Harman/Becker module. Only one MOST plug connected (2 wires), DIP switch ON: 1,4,6 .
Everything is working well.
