Anyone know how/if VW ever updates the firmware for their head units? I've experienced some bugs in the handoff of audio between the head unit and my iPhone in CarPlay, that I'm pretty sure are head unit related and not iOS related. In particular, going into reverse (which will typically duck the audio) while CarPlay is still connecting itself, will oftentimes result in no audio from any iPhone source. When you go to adjust the volume, the volume slider will be gone - it does not go up or down.
Anyone know how often VW updates the firmware to address things like this? Just curious of past experience to know if I should hold out hope or if they basically ship it and forget it.
