Just picked up an AT4 this weekend and have been working through the learning process on the various "systems" on this new generation. One thing I've noticed and was wondering if anyone had experienced and if so how it might be resolved is when an iPhone is connected via bluetooth it seems the infotainment system changes the ringer volume on the iPhone. At first I though I might have turned it down but I've verified it a couple of times by starting the truck, having bluetooth connect then shut the truck off, get out and check my ringer volume. Sure enough it drops down to the last two or three bars on indicator on the iPhone. The other thing I noticed is that when you have it connected via BT and have the music app open, when you change the volume in the truck the volume indicator on the phone goes up and down. I never had this issue with my 14 or 16 All Terrains and if in-fact I'm not crazy I believe this is going to be a bit problematic for folks who experience the same and end up missing phone calls, texts and emails (at least the ones who rely on an audible indication from their phones). Anyone else seeing the same?
