Sorry to jump in here in the middle of the thread but it says Q&A and I have a Q. I recently went on a trip and the truck sat for 10 days. I got an alert from my app saying that the battery level was low but when I got back home, it was fine and everything started right up. My question is this. Has anyone experienced a situation where the audible sounds in the truck have changed? When I returned home, all of the sudden the audible tone of the back up sensor alarm was different and I was getting a different tone in the cab when you open the door with the motor on. I haven't had a chance to look at the settings to see if this was changeable but when I got in this morning, everything was back to normal. Anyone else ever have this phenomenon?
