So, I just updated everything that could be updated.....firmware, software, everything. Now the volume is much lower than it was prior to the update, it will connect to the Grom via bluetooth but not to carplay and if I connect it to Grom via bluetooth, the volume goes back to what it was. But as soon as I plug in the cable so it will connect to carplay, the volume drops. And before anyone asks, when the iPhone is connected via cable to carplay you cannot adjust the volume on the phone. I swear I'm gonna pull this thing out andf throw it in the f'ing trash. It's a damn good thing this isn't my daily..........
