Hi all, 

Wanting to upgrade/install a musway amp but the seller wants to see a picture of the harness so he can send me the right one. Ive no idea the location of this unit, nothing in the glove box. Does anyone know where it is? 2020 Q7 with standard sound system. 

 

It might be under the front passenger seat or one if the boot side panels. 

Thanks, most likely on the right side panel but looks effort to take apart will update when ive had a go.

Glad you've found it, please keep us posted on how you get on 

Well I thought it was on the rear panel turns out its behind the glovebox, 3 screws on top, two below have to remove a small plasic panel on the right side of passenger footwell to see the right bottom screw. One on the left side panel which you have the take out first. 

I dont think I have a sub, so flush sub install pending. Ill be adding a musway m6v4 amp/dsp with the MMI just waiting on supplier to send me the right harness now I know what it is.
