Hey everyone. I've been gone for a long time but getting back into things now. Recently got this HU. I use an iPhone 5s running Spotify. The problem I have is when playing Spotify thru wire or wireless the volume on the HU maxes out around 26 once I click 27-35 there is no increase in volume. On CD and radio the volume increases all the way to 35. Does anyone have a clue why this does this and is there any way to remedy this? My previous HU did not have this issue KDC X 395 Thanks Willy
