I just got my remote display installed into my 06' GTI at a car stereo shop yesterday and the remote display mute button doesn't mute when you hit it.
I have fooled with the main V1 unit and made sure the muted volume slider was set low...
I tried fooling with the rubber button on the remote display to see if I needed to hit it harder or to the left or right...that didn't work.
I did notice that the shop that installed it swapped the RJ11 cables around, and used the RJ11 cable that came with the remote display, for the main V1 unit, and they used the RJ11 cable from the main V1 unit to the remote display. Other than the little connectors on the ends, is there any difference in those 2 cables that would cause this problem ?
Any help on this would be appreciated. I can't figure out why my mute won't work on the remote display, everything else works fine.
